(The fare chart is in Chinese, but I think anything beyond a local stop from TPE is 91.)

Going to the Aloft, the bus drops just to the E of it, at the intersection of Minquan and Linsen. If you look at Google Street View, you can clearly see the bus stop in the middle of the street. That is ~150m from the hotel entrance.
