David was a fantastic host, super responsive and very helpful with everything we needed. The place was nice and clean and private. It also had everything you will need.
The walls are a bit thin towards the outside, so I heard a lot of construction in the mornings. The shower pressure was really low which was unfortunate. Also, my biggest inconvenience was the location. It was quite central in shinjuku and close to a subway, but the place is located very close to the red light district of kabuchiko and there are love hotels and a bunch of other nightlife activities within a small walking area.
If you are okay with the nightlife, then the place is fantastic and David is a great host.
