This apartment is just ok. It was cold during our stay because there is only one old heater that doesn't work very well, so the bathroom, kitchen area was always cold, and sometimes even the tiny room wouldn't warm up enough. The "futons" were more futon toppers, and I know because I stayed at other traditional Japanese ryokans with real futons, so not great for sleeping. The location was just ok, in that it was about a 13 minute walk to Iidabashi stop, but not much else was around, other than other apartment complexes. Nearby is the better area of Kagurazaka. The bathroom is the worst one I had during my trip in Japan, so that was sad because they are so good at bathrooms in Japan! They have Non-smoking signs posted all over the apartment, and I mean everywhere, so that was a tacky touch. None of us smoke, but even if we did, one sign would do the trick. I don't think the apartment is run by a person, but by a business. It did not have a cozy feel at all. The positive is that it was clean, and the self check-in was easy. Check-out time is very early for an Airbnb or even a hotel, so be aware of that. We had a flight to catch anyway, so left before the check-out time, but 10am is early.
