Me and my cousin were staying for one week in Han's apartment. The communication was before and during our stay was great and check-in was easy. The apartment is located near Otsuka station which is on the Yamanote line and takes you to every important location in Tokyo.
The room itself was very clean and also new. The bathroom was spacious. There was enough space for two people to live comfortable.
We had a great stay at Han's place and I can definitely recommend it!
