I stayed in Paul's Airbnb for two weeks, and it was a really great stay. I met Paul in person, and he showed me around. The location is about a 5-7 minute walk from the Taipower Building MRT (green line), and half a block away from the small Shida Night Market and a 7-11 (great for late night eats). The Airbnb is a private loft with a private entrance above the 5th floor, where Paul's son lives. Note that this is a walk-up, so those with mobility issues or a ton of luggage might want to look elsewhere.
With the two private outdoor patios considered, this place is huge. The larger front patio has a little extra walk up where you can stand and enjoy a view of the city, including Taipei 101 in the distance. There is also a washer/dryer outside, which was super convenient for me given my longer stay. The two air conditioning units inside helped cool down the space quickly after a day out. I also worked for part of the stay, and the dining area was comfortable to set up my laptop (good WiFi as well). I also loved all the natural light this place had.
The one other important thing I'll mention is that there is no standard shower available. There is a bath tub with a handheld shower, which I got used to using after a few days. And since splashing water outside the tub is a given, there is also drain on the bathroom floor (just make sure most of the splashing occurs toward the window).
I would absolutely stay here again!
