The studio is well-equipped for long stays and is in a quiet location. I enjoyed my stay here. You will find convenience and grocery stores nearby such as 7-Eleven, FamilyMart, Ozeki and Maruetsu Petit. The Nakano-fujimichō Metro Station is the closer and is a pleasant short walk from the studio. You can easily reach to Shinjuku Station in a matter of minutes using the Tokyo Metro Marunouchi Line.
The check-in and check-out process are easy and I never needed any assistence. The bed is quite spacious and comfortable. The kitchen has a refrigerator, microwave, oven and a portable stove. The bathroom is clean and in good conditions.
I would stay here again. It is perfect for long stays and I recommend it for those interested to explore the special wards of Tokyo such as Shinjuku, Shibuya, Nakano, Chiyoda, Suginami, etc.
