We enjoyed our stay in Shinjuku very much! We could walk back home from Golden Gai, the neighbourhood is very lively, but the apartment very quiet as it is situated in a side street.
When we arrived, we had a problem with the key. But Dong replied within minutes and was very friendly and willing to help - excellent service.
The apartment is as it appears in the pictures. Small, but all you need for a good city trip! Would recommend!!
