The place was quite dusty and we had to buy an air purifier as some members of our party have breathing problems and are allergic to dust. Despite a few other things odd about the establishment, the host was always so nice and ready to jump to your aid if you had any questions or concerns!
One thing that we didn’t consider was that the building was not near a JR-Line, and we often didn’t use our JR Passes while in Tokyo. The building is near Asakusa station which is a Tokyo Metro line that you use a Suica card with.
