I stayed for a work trip for almost two weeks and this was a great little base of operations. Having the kitchen and a washing machine available meant that I could make breakfast in the mornings and do laundry in the evenings. The location is really convenient, tucked away off of main streets but 5 minutes away from the Tokyo Metro Ochiai station in one direction and 5 minutes away from Higashi-Nakano station in another direction. The host was very fast to respond and resolved any issues quickly. I would definitely recommend this place to others and will consider it again for myself in the future.
