I booked a bed for two in a four-bed room. It's small but manageable for a short term stay. All essentials were provided. Sumiyoshi station is out of the way from central Tokyo, but also accessible by transit. I stayed for two nights during Golden Week so did not meet anyone from the AirBnB but received clear instructions on how to get into the guesthouse. Would only recommend if you don't mind the extra commute since it's in a residential area.
