We truly enjoyed our stay. I recommend the host and this room.
Good:
1) Location - really useful and easy to go anywhere with numerous places for food. Moreover, it is really close to Tokyo Sky Tree.
2) Room - incredibly clean, neat, well-prepared. If you like hot bath, it can be prepared automatically just by pushing one button like a magic!
Negative:
1) Too slow wifi. It was impossible to enjoy the internet in practice.
2) No elevator. If you have heavy stuffs, you should be ready to lift them upstairs.
