They gave us a family room for 4 adults and a double room for 2 adults - both rooms are of the same size and same types of beds. So the family room felt a little castrophobic to me. Facilities are pleasant, the breakfast range is great - we like it.
Location is not so good as it is far from the night street market - will cost you around TWN$200 to TWN$250 for one way taxi ride to get there. The hotel counter provides currency exchange and the rates are comparable.
