There is nothing I didn't like. I advice you to stay here, whether you need a romantic get -away, or a nice family vacation :)
I visited Venice twice and each time I stayed at Antica Dogana. This small Vila in the port of Cavallino - Treporti is absolutely amazing. I think this should be part of your Venice experience. It is comfy, friendly, very clean, romantic and relaxing, weather you visit it during summer, or spring. To reach Venice you can take the boat in front of the Vila, thus even though it is not in the "heart" of Venice, the almost 1 hour travel by boat is beautiful and it's worth it :). The owners are extremely friendly and helpful. I wouldn't stay anywhere else, should I ever visit Venice.
To get there quick, from airport, call at the Vila, prior to the departure and the staff will provide you the directions to get there.
