I was staying in Tokyo for about 24 hours so I only needed a place to sleep. This placed served that purpose. The staff speaks English, and answered all the questions I had.
However, I have had better experiences with Airbnb. This place was overpriced for what it is because the building was covered in plastic/tarp because it was having some work done. This was not disclosed to me when I booked. The rooms are smaller and older than I expected. The bathroom smelled of mold or rotting water.
I paid total of $102 per night for this room, but I have paid less for somewhere that's cleaner and newer with more space. So I'd have to say you can find better places for less if you look.
