Stayed at Ohkubos place near the time of Golden Week. Great place (small but typical by Japanese standards) which is close to everything. In the Shin Okubo area, you have lots of nightlife and dining options. Surprised how close to Shinjuku it was - probably a ten or fifteen minute walk. Close to the station (5 minute walk) and is on the JR Yamanote line, so great for those who have a JR Rail Pass. Even though it's in a busy area, room is quiet and didn't hear much. Don Quixote, 7-11 and a grocery store near by so never get hungry or without an amenity. Good and quick communication from Ohkubo so happy that I stayed here.
Thanks!
