Jay's place was exactly as described. Spacious for a Tokyo apartment, clean, and with all the amenities you would need for a great vacation. Jay even provides some items you may have forgotten (e.g. iPhone charger, headphones, plug adaptors, hair dryer, bathroom essentials like shampoo/conditioner, etc).
Jay was very easy to communicate with, and gave great directions for finding the apartment. Check-in/Check-out couldn't have been easier. The location in Shinjuku cannot be beat. Just a 2 minute walk to the Shinjuku metro station, and walking distance to great shopping, restaurants, Golden Gai area, etc. Would absolutely recommend renting Jay's space for any trips to Tokyo. You will not be disappointed!
