Overall an excellent experience and I will stay again next time I'm in Tokyo.

The location is convenient (~10 minute walk from Uguisudani station), and fairly quiet. Uguisudani will give you access to the Yamanote line, which is a primary train line for reaching all of Tokyo's tourist locations such as Shibuya, Shinjuku, Ueno, Akihabara, etc. I was able to check-in early around 10AM and it was quite flexible.

The room itself is similar to that of a small apartment, and includes a private bath and toilet, bed/pillow/towel, and overall every imaginable amenity you will likely need. Even laundry detergent packets for the on-site washer. Convenient stores are numerous and close by.

Hisao-san was very helpful and offered me a ride to the station on my way out. His wife also made sandwiches every morning. I stayed 10 nights and it was a much better/cheaper alternative to a hotel, and less intrusive.
