The Old Folk House is a super cute and unique 70-year old Tokyo home complete with kotatsu (warming table), sliding wooden panel doors, and heated toilet seat (which was very important during our super cold late November stay). The house, being as old as it is, is drafty, but the downstairs heater and kotatsu both worked perfectly, and the shower room is way steamy. Mitsu even checked on us on the snowiest day and explained how to use the shoe dryer. The kitchen was clean and useful, the futons were crazy warm, Akanene's handmade ceramics were amazing, and the garden separating the main house from our house was beautiful (they have a crazy huge persimmon tree covered in fat shiny persimmons right now).
The house is located behind Akanene and Mitsu's home, in a quiet residential neighborhood, close to plenty of convenience stores, the LIFE supermarket, and a handful of interesting and tiny bars/restaurants. The Sumiyoshi Station was just a fifteen minute walk away.
Akanene and Mitsu were very kind; Mitsu checked in on us a couple times, to explain use of the heater, circuit breaker, etc, and he even rolled up with a sweet van to drive us and our bags to the Sumiyoshi Station the day we left.
Koto-ku is a little bit far out from the city center (including walking, waiting and transferring, getting from say, Akihabara, to the house took between 45 min to an hour each way) but my boyfriend and I agreed that staying here was completely worth it. It is literally the cutest AirBnB I have ever stayed at; in fact, it was so cute that it killed us, and I am writing this review from beyond the grave <3
