Pros:
Walkable (20+ mins) to a few main attractions such as Huashan Creative Park, Contemporary art museum, Ningxia Night Market and Taipei train station. Although if you come during the hot or rainy season, then a 20+ min walk may not be suitable.
AC works really well and is quiet. Queen size bed. Should be good for two people.
Elevator building with luggage storage on the 6th floor next to hot and cold water dispenser.
Cons:
Ten minute walk to the MRT was harder than I thought because it was so hot and rainy during my stay.
Amenities are at best motel-grade. No microwave, no chair for the desk, no three-prong outlets. Towels and bedsheets are bleach-heavy. Scruff marks on the wall and discolored walls on the balcony. The place is not as cozy as pictured.
Building is older and smells strongly of mildew; I hold my breath every time I use the elevator. It doesn't smell inside the room.
Communication is slow; takes at least two days to respond. Check in and check out times are not flexible.

Overall if you wouldn't be spending too much time in the apartment, this may work for you. Though I was really hoping for a cozy place and I wouldn't be staying here again.
