Masami's place can be found in a very relaxed area of Tokyo which itself has many restaurants and shops. Shinjuku is only two stops away on the Metro (the station is very close) and we walked back from Shinjuku one night in about 25 mins. The place is very clean and quiet with easy to understand instructions. There is also an incredible view of Shinjuku from the outside staircase at night. We would stay here again without hesitation.
