The apartment was superbly clean with all the furniture and home appliances in perfect condition. Homely, absolutely quiet by night, a place where you can rest and relax without troubles. Really well placed and connected with Shinjuku station so it's really easy to move around Tokyo and surroundings from here.
It's also spacious, we were four people and stayed for nine nights and we never felt uncomfortable.
And last but not least :). Koichi is the perfect host, so kind, friendly and generous (yummy gifts), always ready to help you if you have any problem.
We felt like we were home, thanks for everything!
