agoda may give better price than minsu.
Airbnb may be more suited for either lone traveller or large family, looking at how taiwan is set up for airbnb in general.
I had source for it in taichung, taipei and keelung, and i concluded not worth the money and effort as they are usually no where near amenities or train station. If u hire driver, it makes sense to airbnb
and the space wise, hotel can be cheaper and better.
yangmingshan, on the other hand is different story. worth looking at airbnb on that region
ps- i am a host and i also stay in airbnb
