Hung was spectacular throughout our entire visit. He met us on our first night, despite delays in immigration, and offered helpful tips. He went out of his way to help with things, answered questions promptly and was always willing to help; case in point being when he offered to find a last-minute ride for us from the airport when he found out we were not taking the MRT into Taipei as we initially planned.
The apartment itself is a nice, cozy place walking distance from the Zhishan MRT, Sogo and other things in Tienmu. Hung provided detailed directions to it and we thoroughly enjoyed our stay.
