It is an officetel arrangement. You can get picked up from the airport and driven to this place for free or you can take a free-shuttle to the complex. You will be provided with the access code for your room. If you want an internet connection, you will be provided with a router that is capable of communicating at very slow speed.
The room I was in was arranged with three single beds, indicating three back packers can share the room. A rather large one-room with cooking facilities, refrigerator, and small bath room is okay all you needed was to crash overnight before you fly to the next destination at an early hour.
Downside is the iffiness of if linen was replaced and kept clean and spartan amenities. You may have to dry your showered body with a 1' x 2' towel in the morning.
The room is good, finding it was tough. my family and me came late due to a transit delay in taipei. upon arriving at the airport, it was already midnight with no shuttle service as said by the others. took a taxi and halfway he cancelled the meter.. we couldnt argue much since we were already halfway.. circled the same building twice. wrong building.. got down and kept asking people where this place was. no one had any ideas. a kind korean air pilot helped us after ee chanced upon him while we were lost. he asked around and found us the place.. he was also shocked that there were no signs of the guesthouse explicitly displayed.. lucky he chanced upon the same convenient store as stated in the previous post. overall the room is good but finding it was really hard especially when you come late. no one will be around to receive your call.
