About Karat S

Buses are the most affordable means of transport with a large number of terminals across the country and convenient timetables to help you plan your trip. Buses is a convenient option both for those who travel on a shoestring budget and those who do not want to compromise on comfort. Karat S offers bus service with an online reservation available. Before booking your ticket, read other travellers’ reviews to choose the best option.

What are the Bus Classes & Prices of Karat S?

The price of your bus trip will depend both on the destination and the class of your ticket. Note that not all ticket classes are available on certain routes yet for longer trips there is almost always a good choice of options. Opt for a sleeper coach for the most convenient overnight trip. Sleeper buses are usually equipped with berths or soft reclining seats, feature an onboard toilet and your ticket may also include other perks like snacks or even a lunch. Taking a night bus is also a good idea if you want to save on your hotel room. During the day an express service is often the best value for money as it makes less stops than an ordinary or standard class bus and travels faster. On some routes it may be crucial to choose the right class as, say, an ordinary or second class bus may need some 6 hours to cover the distance the first class or express bus travels in two hours!

Pros & Cons of Bus Travel

Pros of Bus Travel

  • Buses usually boast the widest network of destinations covered. They travel to the places you cannot get to by plane or even by train

  • Travelling by bus is easy – there is no need to arrive to the bus terminal much in advance, and the check-in is usually a very fast formality opposite to air travel

  • Bus tickets are very affordable. Yes, there are costly first class or VIP options but is you are on a budget, bus is the first means of transportation you have to think about

  • At the same time, there are different classes of service to suit any budget. If you are after a higher level of comfort, buses get you covered, too.

Cons of Bus Travel

  • Intercity bus terminals can be located outside the city centre in the outskirts. It means you will need to calculate extra time and money to get there. In certain destinations getting from the bus terminal can cost you more than you would expect because only a limited number of transportation companies is allowed to serve the route – and prices may be inflated.

  • During busy weekends or high season buses serving some tourist destinations may run out of schedule and require advanced booking.

  • While buses are not as weather dependent as ferries, bus trips can also be delayed or cancelled due to bad weather or road conditions – keep it in mind if travelling during certain seasons or to certain destinations.

Corruption. The bus was quite comfortable. The bus driver told my friend that they couldn't get in the bus without the ticket in paper. However, they proposed them to pay extra (250 dinar) so that he could get in. He didn't explain me anything, because he didn't speak English (or he didn't want to), so MY FRIEND had to told me that I had to SUBORN the driver, so that he could look for my name in the list. I swear it is the last time I travel with you.

Great driver but clearly very tired. Clean bus and easy booking. The driver was clearly tired on the long stretches and I watched him nod off as if falling asleep 3 times which made me extremely nervous. The rest of the journey was fine and I was prepared to leave an excellent review as otherwise he was a fantastic driver but this CANNOT happen- open the window, put on music, drink loads of coffee or something but you should be able to do 2.5 hours without an issue or don’t come to work. Next time I will probably take the train so I don’t have to worry.

Other issues. Clean tidy on time. What is with the paper ticket requirement. You pay online get a qr code and yet that's not good enough. If you are going to do that should just tell people to pick up ticket at the station and have them waiting. Actual flix bus has PDAs why doesn't this sub contractors. Also why no toilet on board. This is ok but not up to the flix bus standard.

Reliable and punctual. Everything was fine and we arrived even before the scheduled time. Printing a ticket is a hassle. They should accept a mobile ticket (and state this fact when booking).

Convenient Travel from Plovdiv.to Sofia. Bus was easy to find and it was a comfortable ride. Travel is about 2 hours. I had a language barrier but could figure it all out. Driver was excellent and drove safely and at a good speed. I never felt worried about the driving. Ticket must be printed on paper. I didn’t know this and had a bit of stress getting the printed ticket before departure. No bathroom on board, which I think was uncomfortable for a couple of riders who did not know.

Great busride, but unfriendly driver. Bus itself was great, with airco and comfortable chairs. Bus driver didn't speak English and was very unfriendly. Bus ticket needs to be printed, while we got a QRcode, what is a waste of paper.

It would be great if it doesn't require to print the tickets. Buying ticket in advance online, available to cancel the ticket it's good, very flexible. It required to print the ticket!! Very inconvenient and tree killing while the confirmation on the E-mail has the bar code.

WELL.. Confortable seats and charger. They weren’t no silence during a big part of the trip. The bus smelled tobacco so bad. It’s was disgusting. We really believe that the drivers were smoking inside. One of the drivers did not stop screaming in every stop that we made. We understand that he had to warn the passenger that should go down the bus but, let’s respect the other passengers. The truth it’s that tobacco smell was the most unrespectful thing. Wifi only in Istambul. When you cross the border nothing.

Bad company. The ride from Sofia to Plovdiv the same day was fine, we arrived earlier than expected. The bus driver and the woman from the desk-ticket office were very rude, because you can not have the ticket on your mobile phone and you need to print it.. Plovdiv-Sofia, the ticket office gave us a ticket with the incorrect date, and we could not get on the bus. The other buses for late afternoon were full, so we had to buy a train ticket, and the company didn't do anything for us, they only wanted the money.. And again, they were rude. If you are going from Sofia to Plovdiv, or the other way, please choose another bus company.

Easy to use Pretty comfortable and wasn’t too full. Silly that you need to print the ticket rather than keeping an electronic version Would have been nice to see the route and bus changes pre getting on as we don’t speak Bulgarian.

Good. Cheap tickets and buses were frequent. We missed our bus due to the bus we were catching into Sofia being delayed at the border from Serbia. The lady at the ticket counter was very unhelpful and unsympathetic. We had to pay full price for the new bus ticket.

Excellent service, comfortable coaches and on time. Everything worked perfectly. If you book online, the seat number isn't written on your ticket, but there is a member of staff with a list of passengers' names and allocated seats to help.

Bought a ticket from Burgas to Budapest. It didn’t say anywhere we would change bus in Sofia. There were cheaper tickets than this one but I chose this because I thought we would not change buses. At least it should have been written somewhere!

Make sure you get a "real" ticket. The online booking confirmation I printed out was just that - not the ticket. You have to exchange the confirmation for a real ticket at the Karat-S desk before boarding the bus. That's important because all tickets are allocated seat numbers. The bus driver wouldn't let us on in Sofia, but did after checking with the Karat-S desk. But the woman there should have given us proper tickets with seat numbers. We (and other tourists) had to move twice before we found non-reserved seats. The woman at the Karat-S desk in Plovdiv was very helpful and printed out proper tickets with reserved seats for the return journey. Now I know exactly what to do, I would definitely use Karat-S again!

Friendly staff, good bus. Friendly staff Clean and comfortable bus Good timing. When you sell tickets, the place of departure should be specified. We almost missed the bus because we couldn't find it. You should add that the bus goes from office 126. The drivers should take turns driving, as our driver was visibly tired.

Stifling Hot Journey. Ride was smooth and left on time. There was no air conditioning and the thermometer reported temperature of 31’C. Several passengers requested the driver do something, which I guess he was unable to do. The entire trip was airless and made us feel quite unwell. Dangerous to travel like this at the hottest part of the day.

Good and Comfortable coach trip. Comfortable seats and good air con. Got from A to B fast and simple. I didn’t like that there was no seat number information on my ticket that I bought online. Luckily the host of the coach had our names and seat numbers on a piece of paper. Also would had been good if we could use the toilet throughout the journey.

Good to prevent queuing in the bus station and also to ensure you have a ticket in the time you want- No queueing - Bus was comfortable and clean- No seat number printed in our ticket: the driver didn't know which was our seat and we had to move around several times as people that bought tickets in the station had their number printed. - For the return ticket we went to the ticket office to check if we had seats assigned. The ones assigned were the most uncomfortable ones (not enough space for legs), but we're not sure if this is always the case or not. - Tickets MUST be printed out. They're not allowed on the phone.
