Booked a bed in the female dorm at the very last minute as my original plan was to stay a night at Taoyuan Airport to catch a 6.50am flight to Tokyo. Instead, rested for a few hours here and took a cab to Taichung Bus Terminal for bus to airport.
Friendly owner with a hand-drawn street map of the surrounding area (laundry shop listed on map was kind of dirty though; managed to find a cheaper and cleaner one around the same area instead). The toilets were clean and the beds relatively comfortable. There is not a lot of space for socialising on the ground floor, but it did not bother me as I was there for a short period.
It was fortunate that I got that last bed, although instead of sleeping I did make some new acquaintances (all solo travellers, but everyone had something in common with at least one person in the room).
Was able to leave the key without any problems. Thanks for the comfortable stay!
