Stop what you are doing, and book the Palazzo da Mula now. If you are feeling its a little more pricey than what you were hoping to spend, please trust me, book this place. People throw around the word palace pretty loosely ... this place, its an actual Palace. From the 13th century architecture to the 17th century frescoes on the ceiling, to the sweeping views of the grand canal with evening serenades from gondoliers just below the floor to ceiling windows, to the beautifully appointed furniture you can not go wrong. I have traveled the world over the last 25 years or so, I've stayed in some amazing places, none is a close second to the Palazzo da Mula. I could go on and on about it but you get the idea.
Massimo and his daughter Diane were fantastic hosts. He was away on business so Diane handled the welcome. She was so friendly and helpful. When asked, she was full of great advice about Venice, what to do and where to eat. She definitely made our trip better. She also was willing to tell us all about the Palazzo and its history. Massimo also was fantastic, extremely attentive. When I needed him for a minor issue which was my fault, he was right there on the phone to help within minutes.
Normally I would "recommend" that you stay somewhere in a review. It's not the right word in this instance though. I *insist* that you stay here. It's an experience you will not forget.
