To get the keys, it is quite a distance when you arrive at the place, which is a bit of a pain. I also had trouble getting the key out of the box.
The apartment is miniscule, but this is Tokyo. There is absolutely no luxury in the apartment, but everything is in working order.
Compared to other Airbnb, you feel no personal contact whatsoever with the owner. I received messages reminding me to do my online checkin (requiered process in Japan) regularly, although I had done it. At one point, I asked Yuri why I was getting these, did I do something wrong, and he replied that it was an automatic message. Little things like this removed the personal aspect of the apartment.
It was not all bad, Yuri does respond quickly when you do have a question. The place has a washing machine which is good when on the road for a long time, and it is located relatively close to Ebisu (7 min) and Shibuya (10 min)
