We had a fantastic stay over at Izumi's place. The house had plenty of space for a family of four. The beds were comfy and the place was very well kept. The location was great as it was close to the stations and Tokyo Skytree too. We could even see the tower from the windows of the house. Izumi was really kind and helpful as well. It's a great place for a family of four however it will become a challenge if one were to bring a large luggage into the house as the room is on the 2nd floor and the stairs are very narrow. Overall, it was a great place and I'd highly recommend you stay here when visiting Tokyo.
