Sai's place is a flat with a loft in a relatively new high rise. The location is good, it's very close to a lot of buses, Youbikes, and the red metro line. There's also a pretty good night market within a couple minutes walking distance. Everything in the apartment is nice and works well, and it's quite spacious for the area. The gym is pretty minimal, it only has cardio equipment and a couple other small pieces of equipment, but having a gym at all is pretty rare for Taipei.
The only minor issue I had is that even though the walls and ceiling are reasonably well insulated, the tenant above occasionally had loud footsteps late at night. It also made me worry a bit about bothering the people below.
