Kotaro san and Kei san's house was the absolute perfect place to stay in Tokyo. Their house is clean, with full amenities, and is near a major train line. We were given a complimentary portable wifi hotspot to use around the city. And Kei san made us breakfast every morning, which is important because Kei san is an outstanding cook. Also they recommended a restaurant in Tokyo which is now my favorite budget sushi place in the world.
