I stayed in the Grey room for one month. The grey room shares a bathroom with the guests in the yellow room. The room is very small so don't expect to be hanging out in your room a lot. Also, there is no outside window in the room, the only small window looks out onto the living room. There is no a/c in the room, they provide two fans in the room to keep it cool and you rely on the a/c in the living room being strong enough to cool the grey room. The fans did a pretty good job of keeping the room cool but there were a few days when it was really hot and i could not get the room to cool down. Other than that, I had a great stay here. The owner comes almost daily to tidy up the common areas and bathroom so the place stayed clean throughout my stay.
