I had no trouble finding Dat's place thanks to all the information (descriptions, pictures) provided to help, and it's close to the train station and some convenience stores and restaurants. I found one of the keys didn't always want to turn in the lock, but it always worked after a few tries.
I didn't notice any smells like some reviews have mentioned. Maybe it depends on the weather or how each guest treats the room. I also had no issues with noise from the other guest room, though I'll agree the walls are pretty thin as sometimes I did hear the other guest rustling plastic bags in the evening. Thankfully they were considerate and quiet.
I found the bed comfortable enough for me and I slept quite well. There were a number of interesting books available in the room (that I had no time to read) and a jug of water prepared. Walking around the neighbourhood was nice.
I would stay there again, it's just a slight gamble hoping the other guest is considerate.
