My husband and I had a 12 hour layover between flights and needed a place to stay.
Guey Lin hotel is nicely located just 20 minutes from the airport and provides all the basic amenities for a quick stay. Rooms are clean, toiletries provided along with coffee/tea in room. We were leaving pretty early the next morning and would be missing the complimentary breakfast...the staff was kind enough to make us a little sack lunch with a basic sandwich and juice box for the road.
Hotel is easily accessible via taxi (~$10US one way) or via express bus #1841 (~$1 or 26 Taiwan Dollar). Get off at Nankan. From there it's a quick 2min walk. More
