The Grape House is swell, in a quiet, more locally driven neighborhood with friendly businesses and people around. Barely any other tourists, not such a bussle as the rest of Tokyo, really enjoyed the relaxed community feel of the area. Which also means the cute shops and restaurants take a bit more work to find but when you do are so incredibly lovely.
The place itself was larger than most BnB's in Tokyo we looked/stayed at which was also a welcome change. Naomasa is a very quick and thorough communicator, no issues at all! Solid spot to stay.
