We really enjoyed our stay here. Our room was very well equipped (coffee capsules, kettle, hair dryer, fridge, bath amenities, toothbrush, towels, drinking water etc.) and it was very conveniently located (close to Higashi-Shinjuku station and several convenience stores). The room and bathroom were also both quite spacious (I've been to some rooms in Japan which were so small that there wasn't enough space to open my suitcase but here we were able to open both our suitcases comfortably).
A big thank you to David for being a great host. During our stay he regularly checked up on us through the app to make sure that we had everything we need (like towels, help getting around, etc.) and instructions for check-in and checkout were very clear.
