Reliable service, got us where we needed to be without any issues.
The bus was about 10 mins late leaving, which really doesn’t matter to us - just something to note. We got a free bottle of water on a comfortable bus that transported us safely from Chiang Mai to Chiang Rai.
The bus broke down halfway but that's not their fault. Had to wait for a bit, but they stopped at a place with a small shop and toilets so it was fine. There we waited for another bus to come pick us up. Overall the busses were comfortable and I would book again (by the way I read some other reviews that there are no toilets in the bus, but there are! In the back!)
