I was very grateful to spent a night at Grapehouse. They are extremely nice people, and I was very glad to be able to talk with Shoko (and hope I will meet her again !)
The guest house is very clean, well equiped and with a very nice situation - Koenji is one of my favorite area of Tokyo, I recommanded if you're looking for record shops and thrift shops ;)
I recommanded this adress ! Thank you ladies !
