Can’t beat Kota’s house for proximity to the JR Yamanote Line, cute little local restaurants, and people just going about their daily life. The house gives plenty of space for sleeping and hanging out, and is a great example of traditional housing with lots of cool design touches. The only caveat is to be prepared to dress warmly during the winter, and the house is not well insulated, and the heaters will have to run pretty consistently to keep the sleeping areas warm. The shower and bath area is pretty frigid before you get the hot water going. Also know that you’ll be sleeping on futons on the floor, which is very comfortable especially if you layer a couple on top of each other. These are not critiques, just something to know if you are sensitive to these things. We had a perfect stay at Kota’s house and felt great coming home to it each day at the end of our Tokyo explorations. Recommended!
