We had a good stay at Ryota's. The apartment is much bigger than standard Tokyo, and great value for the location.
On the downside, it lacks stylish decor that some personal homes have as it is probably just a rental business with basic amenities.
Also there is no lift and pretty steeps stairs, it was fine for us but might be a problem for some.
If looking for a central, spacious place in Tokyo I would recommend Ryota's apartment.
