Yukari and David were great hosts! They were very responsive to our email requests.
Now onto the place. It's a very beautiful and modern home and super clean. Although there a lot of stairs, it was very roomy and comfortable. Additionally it's in a great location and very easy to get a cab if needed. The only negative is the shower is on the first floor and the bathroom is all the way on the third floor so it's a little inconvenient.
I visit family in Japan every two years and would stay here again!
