Jenny was a great host. Her place is a little odd, but as other reviewers mention, there has been a real effort to make the room nice. Of all the Air Bnbs I've stayed at, this was the most "hotel-like" in the sense that the room is clearly for sleeping and that's about it.
If you're looking for a resting spot while you're out and about in Tokyo, this is a great spot.
Note: The stairs to the room are very steep and there isn't an elevator.
