Shin's place was great. The pictures accurately depict the apartment - it's definitely cozy and is perfect for two people. The shower and laundry were very easy to figure out as Shin leaves you a handy guide with English instructions.
The location was ideal - we were about a 15 minute subway ride to Shibuya and about 5 minutes to the centre of Shinjuku. All other areas were very accessible from his place.
I would definitely recommend this apartment and would stay again if I return to Tokyo!
