Our points stay at the Hilton Molino Stucky in Venice was absolutely amazing. It is in a quiet area on Giudecca Island, which is a welcome escape from the congested areas of Venice. With diamond status, they gave us a beautiful and very comfortable large 2 bedroom suite for our family that overlooked the waterway in front of the hotel. The rooms had real windows that opened up completely. We were lucky to be there when the weather was crisp and clear, and the fresh air with sounds of water lapping in the waterway in front of our windows was intoxicating. It was a quick ride to other parts of Venice on either the hotel water shuttle or the vaporetto. There is a also a fantastic rooftop pool and bar with the best views of Venice. I have stayed in hundreds of Hilton properties and this stay was the most memorable. But I am sure you will have plenty of other great choices in Europe. Good luck!
