I stayed at Ayaka’s house with my girlfriend for exactly one month for cherry blossom season. It was my fifth time in Japan so I knew most of Tokyo well, but we were looking for a more relaxed and ordinary stay with Ayaka and got exactly that. Her and her son were often available to spend time with us and do all kinds of things such as playing basketball, going to cooking events, going to meet and greets, and many other things. It was a very comfortable and enjoyable experience spending time with them.
As for the space itself, it is located in close proximity to Tokyo University as well as many convenience stores, restaurants, and subway stations, as most of Tokyo is.
The kitchen is fully equipped and breakfast each morning was included, which was a big help for us. The room we stayed in had a bed, desk, closet, refrigerator, pocket wifi, and many windows. It lasted us well for a month and offered us a degree of privacy by being separated from the other floors. There were also laundry machines available, which is convenient for extended stays. The room was also visited by cleaners regularly, once every week or second week I believe.
Lastly, the value was very favorable and the initial point that sold us. It is relatively inexpensive compared to most areas in Tokyo, as it is in a more relaxed and homely neighborhood compared to the common tourist destinations of Shinjuku, Shibuya, and Akihabara.
All in all, if you will be staying in Tokyo for an extended period of time and are looking for an inexpensive, tucked away room with a friendly and inviting family to spend time with, this is a very strong fit.
