I recommend Naoki’s place very highly. It looks exactly as described, an 8 minute walk to a station serving the Yamanote and Keihin-Tohuko lines and a 15 minute walk to the Ueno station that serves a ton of locations and some Shinkansen as well. If you’re looking for a place that is convenient to Ueno and Akihabara but is still quiet, this is hard to beat!
