Tomoko has been a very friendly host and always responded quickly and clearly.
The apartment was absolutely spotless clean, the check-in was extremely easy and reliable. All appliances in the apartment were very new or in very good condition, beds were comfortable and the washer dryer made it very good for us traveling with a small child to always have clean clothes.
Walking from JR Akabane Station takes about 14 minutes, walking from Metro Shimo station about 5min, which is good.
Only downside was the steep staircase in the building, as we were traveling with a small child who hadn't been to a house with a staircase before, so we had to be extra careful. Tomoko has another apartment in the same building which I guess is very similar but on the ground floor with no stairs.
