Hisao was a very gracious host and provided a ride to the skytrain the day we left. His wife prepared delicious sandwiches for us to take on our journey.
The room was quite spacious compared to other places we stayed in Tokyo.
Check in was a bit awkward at the kendo studio as there was a kendo class going on and no front desk - we arrived 15 minutes earlier than expected and it was very unclear who we were supposed to talk to. We were greeted by a person refusing to believe there was an Airbnb there, and it took a couple minutes to sort out.
Other than that we had a lovely stay. We would stay with Hisao again if we came back to Tokyo.
