I stayed at Sophia's place for a month. My thoughts are below for future bookings:
Pros: The location is excellent as it is near a night market (Linjiang), so there are many food options around. Also, it is within a 10 minute walk to two MRT stations (red and brown lines), so you can get anywhere in Taipei easily. There are also a couple of YouBike stations nearby, and you can bike to the Taipei 101/Xinyi area in about 10 minutes. The room was fairly clean when I arrived, and self check-in was super easy. Also, there isn't too much street noise as it is in an alley. I would recommend this place if you are really care about location.
Cons: The bed isn't very comfortable as you can feel the springs. The room can get musty so you have to leave the window open frequently and use the dehumidifier provided. The walls are a little thin, so you can hear people walking in the hallway.
