I enjoyed staying here! Prior to arriving, Miyabi sent a PDF with instructions to access the apartment and English-translated instructions for the appliances. It was enough space for two people (maybe three), close to the subway stations which made it easy to get from place to place, and close to livelier places in Shinjuku. There are three convenience stores and 24h restaurants close to the apartment so it's easy to pick up snacks or a quick breakfast when you're sightseeing early in the morning.
