Rumika is a nice host who was willing to help us to solve the problems we faced before and during the trip.
The room is tidy and well decorated. It is very specious for four people (like us) to stay. Two bedrooms (with two double size beds in each room) are located in two different floors. The living room and kitchen are large.
The location is convenience and easy to access. It needs about 7 minutes to walk to the Hatsudai (初台) station, which is one station from Shinjuku (新宿) station. There are many restaurants and convenience shops nearly.
To conclude, it is a good place to stay and I highly recommend to those who would like to stay in Tokyo.
