Based on tando’s link, the 1000 NTD is a daily subsidy to the operator of the hotel right? And it seems if you do home quarantine you can apply for the subsidy. Hanns House looks nice but for 7500-8500NTD and not being able to take advantage of the rest of the hotel, I’d probably go for one of the cheaper ones on the list say S Hotel is 3800NTD/night no meals or 5000/NTD/night with meals. Most of the options on the link seem quite good if you are OK with a single room. If there is a standalone Airbnb with willing host and say a patio that you can get to without leaving the “house door” area that would be ideal, to get fresh air. Kind of fascinating how Airbnb apparently removed keyword search in 2016, so there are only two places easily Googleable
