When I first arrived, they did not have the room I reserved 3 months ago and wanted to give me a room in the basement. And for my final day, they told me a pipe burst and I would have to move to the Vienna Hotel, a lower rated hotel. In each instance, I objected, and they provided the room I reserved and paid for up front. Metro deliberately tried to give me a lower quality room than I paid for. I do not recommend the Metro Hotel.
Note how many of the reviews for Metro and other hotels in Taiwan are from Asian travelers who are likely to be in a tour bus/group. I believe Metro tried to shortchange me on my reserved room because they over committed on their tour groups and Westerners are a less important revenue stream, hence I was deliberately lied to by the front desk staff.
The breakfast was just OK, less quality than one would expect for a hotel of this type. Also, wifi only works in the restaurant/reception area, not in the rooms. Really, for a few hundred dollars they could add a router to each floor instead of inconveniencing everyone to hover in the reception area.
Room Tip: Check who provided the review: someone in a tour group or an independent traveler.
