I spent a month at Nao's place and was very pleased and therefore highly recommend it.
The place is quite small as is usual to places in Tokyo, yet even so it is clear that a lot of thought was put into the design and space utilization, so it was definitely enough for me. In addition, the place was immaculately clean (very important to me) and well equipped. Nao also was very responsive and helpful.
Would definitely highly recommend it!
