Comfortable bed and cold AC. About all that matters in Tokyo summertime. It's a close walk to Koenji station, and everything in the apartment works (standard unit bath, tiny but functional kitchen). Be warned that it is very small. I've stayed in a good number of studio Airbnbs around Japan, and this one was definitely the smallest. It would probably benefit from having futons that can be put away during the day rather than a bed filling the whole space. However, if you aren't fussed about having a small space and just need somewhere to sleep and eat breakfast (while sitting on the bed), this Airbnb is great. Koenji is also a fantastic neighborhood.
