Rinako's apartment is nice and cosy, clean and near Shin-Okubo station (which is on the Yamanote Line and is near to many popular districts). There's also a konbini really close by, and many shops and restaurants. It's near a busy street but the apartment is located in a quiet sidestreet !
We had some trouble opening the door the first time, but once you get the hang of it, it's really easy (it's nothing but a heavy door, so if you can't get it open on the first try, it's normal !).
Inside, there were many things at our disposition : snacks and drinks, as well as many utilities,... everything we could have asked for was there.
It may seem small but it was just enough for three people, it didn't feel cramped at all.
I had a great experience and would recommend this apartment.
