My boyfriend and I stayed at Brian's place for over a week while on a family visit. Brian was a wonderful host and stayed coordinated with us from the time our plane landed to the moment we arrived at Da'an MRT, even when we were delayed. He walked us through the whole process and quirks of the house, and sent us numerous recommendations to things to check out in the area.
The location is AMAZING. There's so much to do in Da'an, and Brian's place is mere steps away from the MRT station which we used every day, particularly the red line. Key things (Din Tai Fung, Taipei 101, Long Shan Temple, CKS Memorial, Taipei Main, etc.) were no more than 15 minutes away, including the time it takes to walk from Brian's place to the MRT.
100% would stay again!
