I spent one week at Maki and Yuichiro's house in a wonderful area of Tokyo. The area is nice and the location very central and close to public transport.
The room is nice and has everything you need, the bathroom is just opposite the room and you have your own toilet.
Maki and Yuichiro are the best hosts you could ask for - especially when arriving in Japan for the first time (like me). I felt really at home at their place, loved the chats with them and could even taste nattō (and even liked it!).
From beginning (with the early check-in) to the end (when it felt like leaving friends) everything was absolutely perfect. Highly recommended!
