This was one of the best, if not the best, Airbnb experience I've ever had.
Sayoko has a wonderful family of two adorable, smart, and friendly kids, mischievous yet polite. The family picked us up by car at the subway station when we arrived and gave us great instructions on everything in the house as well as local travel advice. The kids and we played the piano and games together. The mother as well as the girl, Moica, can speak English, and we had great conversations with the mother about Japanese culture, economy, and life, which we didn't get to have with our previous stays. Before we left, the entire family took us to one of the best shopping malls in Tokyo and helped us store our luggages.
If you're looking for staying at a true, happy Japanese family and living their life, instead of at an "Airbnb" hotel, Sayoko's place is definitely the move. Highly recommend.
