When we checked in, we were pleasantly surprised at how stocked the studio was with amenities. Everything was covered from the basics such as toiletries, to the different fabric detergent scents available. There was also a couple of handbooks detailing the check-in process, and an operating manual for the different appliances. The location was pretty good, sandwiched between Iidabashi and Kagurazaka, meaning you're never lacking options. Ogawa-san, though never having the chance to meet her personally, was very responsive, and she does provide a nifty PDF that entails all you need to know to get there and get in.
Now, for the stuff that was really out of the host's control:
-This place gets REALLY cramped for two guests. However, I did come across some info prior that this is to be expected in Japan, and for the price of this listing, we can't really complain.
-Be ready to basically go through government-level clearances, with the amount of times we had to provide our passport pictures and what-not. You basically have to go through a background check. Supposedly, this is the new Japanese rule for Airbnb or something like that *shrug*.
And now, for the things that can be improved:
-The check-in process. Not counting the three codes you need to input just to get the manual key, the problem was doing that check-in on an app in the tablet provided, which requires you enter each guest's personal info and to take pictures of the passports (couldn't believe how many times I had to do this overall). For some reason, the check-in app only allows you to take pictures with the front-facing camera (which makes sense if one is traveling solo), but it's of piss-poor quality. We had to try so many times before my friend's passport could be validated.
