Fantastic location. Walk out the door and you are at the entrance to Dongmen MRT Stn. Take a quick walk down the side alley, and you are in the Dongmen market. Very local feeling to it. And the apartment is a quick walk to both Da'an Forest Park & CKS Memorial Hall if you'd like to get some exercise.
Honestly, I used to live here (before they had put in this MRT line), and I don't think that I could pick a better location in Taipei.
The apartment itself is compact in the sense of it's footprint, but the layout -- and high ceiling -- make it feel both comfortable and airy. And it's a corner apartment, so I found it to be very quiet, too. Bed is in a loft, which is worth noting again. The photos are very accurate.
Cheng Lee handled all communication well, and made the check in and check out very easy.
Hope to return soon!
