This was a fantastic apartment. Such a great location - being a few minutes from St. Marks, but far enough that you can't feel the really touristy bit. Having the bedroom window open to the canal was also very romantic. It's a small canal too, so not noisy or anything.
The only tip I have is if you do plan to do wash, Venice is a very damp place. You will have to leave a lot of time for your clothes to dry. We didn't really think about this, as we are from Canada and our clothes usually dry overnight at home. I would allow for 2 - 3 days drying time. Thankfully our host had a hair dryer available so we were able to use that.
