Quiet neighborhood with nearby grocery and train line. The house was spacious enough to house all 7 of us. It was clean and looks exactly like the photos. The owner also provided pocket wifi, sufficient cooking tools, laundry tools, and even hair styling tools.
The only difficulty we encountered with regards to location was transferring from the airport via sky train. There were no elevators when we transferred to Oedo line and we were carrying 11 luggages in total up and down the stairs and travelling with older people. Going home we just booked airport bus tickets in Shinjuku station which was much more convenient as it is only one station away.
