I stayed in Apt A and it's a perfect place for solo traveler for short stays. Sansan and JD's place is super clean and awesomely designed inside. It's centrally located and walking distance to the MRT stations. I really like the informational binder, it was very helpful. There are Several great breakfast places nearby. It's a safe neighborhood and quiet at night. The air circulation system in the bathroom is great. I didn't mind the 2 long flights of stairs as I had a small luggage with me. If commuting from and to Taoyuan International and plan in taking the express bus, as suggested by SanSan and highly recommend taking a cab from the bus station, it's not far (15-20 mins), but a trek if with luggages. I would definitely stay here when I visit Taipei again.
