Akane & Mitsu's house is amazing! The old house it's actually an detached home in the back. The house is 2 floors, with the kitsch, living room (tatami style), toilet, shower room in the bottom floor, then bedroom on the top floor. Lots of privacy for your group. I think the house can fit 4 people comfortably. With the only 2 of us staying it's such a luxury. Everything in the house was very clean, kitchen has a stove, a toaster, a sink, everything u need to make a small meal. Also tokyo gets a bit cold at night and there is a heater and another space heater underneath their living room table (Japanese style) for the feet. The house is only 8-10 minutes walk to the Sumiyoshi 住吉 metro stop off from the hazomon line. On the last day after we checked out we've toured the near by Skytree and it was so convenient to get to. The pictures don't do enough justice for how amazing this place is, and hosts Akane & Mitsu are so helpful and wonderful. We will come back to tokyo because of them. This place is truly an oasis from the busy central tokyo and really felt like going home after a hard long day of sightseeing in tokyo.
