Hiroko's place is awesome. Very tidy, and clean and has everything you need. We stayed there for 9 days, and I would have stayed longer if we could. All the appliances in the house work and are clean, the bed is soft, and the floor space is big enough for two big suitcases to be open on the floor. The bathroom is clean and big enough to shower or take a small bath.
It's very close to a station and plenty of places to eat and buy groceries are nearby.
I highly recommend this place again to anyone staying in Tokyo!
