The musty smell is real. It is especially bad when you open the closet. Otherwise the hotel is fine, it’s close to Taipei 101 (<15 min walk), metro station (<5 min), and very easy to find a cab. The bed is comfy, sheets are clean, and the shower has good water pressure. My husband and I got a 2x twin bed room and that didn’t bother him (6’2”, 187 cm) . If you can overlook the smell, it’s worth it. Definitely can’t complain given the location and price.
