Check www.betterbidding.com out for your question on which hotels show up via Priceline bidding. There is a search box top center of the page. Just plug "venice" in.

If you want to continue on that site asking for some bidding advice, they will want your specific dates and desired star level. Based on what you've seen in the above search, you likely will have nailed it down to which star level you'd prefer.

http://europeforvisitors.com/venice/ has lots of good detail, although there are many other similar sites.
