Booked 8 nights on Aug 2014, and request higher floor non-smoking room. It is a nice boutique hotel with total of 8 floors (actually only 7, they skip number 4, is a Chinese thing) and upon arrival I immediately spread my personal belongs around the room, all dresses hung, clothes laid nicely on the drawers, thinking for 8 nights might as well makes myself comfy without digging into luggage.
Breakfast every morning offers good selections both Eastern and Western styles though wasn't elaborate as some Asian hotels do but for American travelers it is shocking nice. Room service is fast and I found they make better sandwiches then Asian style meal.
So, enjoy my stay for the first 5 nights, then they told my room will be renovated so need to move, though not happy with pack/unpack everything jammed my luggage, I was moved to a much lower 3rd floor. Boy or boy, the same room layout but carpet stank like homeless, that night I was toss and turn even try to breath with mouth open, not helping. Complained to front desk but really don't want to pack/unpack again. They assured me it will be taking care of when I come back. The next night the odor was slightly improved, I never wanted to move again.
Overall, I would say Hotel Dion is pretty nice hotel as it is convenient located in the heart of Taichung with shopping and transportations. new bus BRT stop just steps, actually 12 steps, Airport bus just diagonal across, can't beat the convenience and price is fairly reasonable.
