Kota's place was amazing. It has been the best accommodation experience we have had so far in Japan. The house is lovely and quaint, and although compact, quite spacious and comfortable. Kota was very helpful and a great host.
Taito is great place to stay in Tokyo. It's close to Ueno Park, Asakusa, Yanaka and right on the JR Yamamote line, making the main areas of Tokyo easily accessible.
