This place has both hotel room ensuite bathroom and hostel dorm type with co toilet and shower room. It is near MRT with 5-8 mins walk and also near the bus stop for airport bus no.1841. It is located next to Poya shop (just walk pass Poya and turn left at its corner and walk until you pass the whole store, you'll see the entrance). The building has an elevator for anyone who has big luggage.
The dorm room is clean and cozy. Each bed has a privacy curtain and electric outlet. The living room has free massage chairs but all menu is in Chinese. They also have free washing machines and dryers for guests to use, just bring your own detergent and softener or purchase them at coin machine (10 NT per each).
The hostel has a lot of shower room and toilet, so don't worry about waiting for a long time to get in. They also provide hair dryers, but for someone who has thick long hair, it might take a while to dry your hair. Some staff can not communicate in English well, but they are willing to support your request.
Their breakfast buffet has both Taiwanese and western food, but mainly Taiwanese. During my stay, most guests are Asian, so I guess that's why the meal is mostly Taiwanese food, but it's a good opportunity to try local food.
