Mo rooms obviously, has unique very nice rooms. I stayed in both the rabbit room and the rat room and they are both very cozy. I liked the rat room better because there was more storage space. The courtyard with swimming pool is gorgeous. There is a bar/ restaurant (though it closes early) and the location is perfect between the night market and the old city.
However, I was not crazy about my stay at mo rooms. My main negative point is that I found the staff to be standoffish and cold. Though some of them were nice, many gave the impression of being bothered if I had a practical question. I got the impression they are also not used to single travelers here. Secondly, there was no mosquito screen on the door, and as all the rooms have individual entrances, there were mosquito's in my room.
In short, Mo rooms is definitely a must do, to experience the spectacular rooms, but it is a one night thing.More
