Great place in a great location.
This is a space in Tokyo, so we knew it would be compact, but it was very functional. The space was clean and we felt at home during our entire stay.
Location is great (3m walk from Shin-Otsuka metro station, 12m walk from JR Otsuka station on the Yamanote line). You can also walk to Ikebukuro. Lots of services around the space.
The host is very responsive.
