The hotel is located not far from MRT Station, the location is good. And for attractions in Taiwan, I think you shouldn't miss Taruko, Alisha, Sun Moon Lake, and you can also go to Danshui. If your credit card is some worldly acceptable ones as VISA or other kinds, I think you can use it in Taiwan, but if it is from some bank in Malaysia, the stores would not accept it. Better change money before going there.
