We enjoyed our stay as a family with two young kids. One slept on the sofa and was comfortable. Kazumi has done a good job of renovating an apartment in and older building. Nice shower and toilet and the washing machine with dryer option was great!
We were surprised to find that there was only one air conditioning unit for the main bedroom as we stayed in summer, but were able to manage.
The apartment is easy to get to just off the Saikyo Line with several different takeaway options as well as other places to purchase necessities in the neighborhood.
