Dong’s place was very nice. It was in an excellent location (about a 15 minute walk to the main area in Shinjuku). It was very small (as to be expected in a main area in Tokyo). We had 3 adults for one night and it was definitely way too small but perfect size for 2 adults assuming you did not bring big luggage. One thing that could be better is having directions for some things in English (we spent at least 5 minutes trying to figure out the air conditioner). There is also a portable WiFi device for you to use (I had rented my own so I would use this one when we were in the apartment since there was not other WiFi in the apartment). Overall a very pleasant stay!
