We had a great time staying at Ban's air bnb. If you can overlook not having a shower it's more or less perfect for the price. It's very easy to find if you follow Han's instructions from the train station myogadani. Also since it is a subway station you can just get a 24/48/72 subway ticket for tourists and see about everything in Tokyo. Our room had new tatami mats, airconditioning, a water boiler, sink and a map of directions to a good bathhouse close by. The futons we were sleeping on looked clean, as did the rest of the appartement. Han also tried his very best in helping us out before and during our stay. He even showed us around in Tokyo!
