The location is fantastic. You can walk 15 minutes in a wonderful area to rich Shinjuku main station and go anywhere. Or in 3 minutes at the closest subway station.
The house in perfectly clean and the communication with Natumi is easy a very quick.
Be aware rooms are very small. We could hardly move in our room when luggages inside.
Bathrooms are ok, but only two showers for all the guests (8 rooms I believe), one for male and one for female, can let you wait a bit to take your shower.
We suggest the place.
