Anna is a absolutely wonderful warm and open hearted host. The room/appartment is located in the lovely and not so touristy area of Dorsoduro (a not touristy area is hard to find in Venice!) and is easy to reach from the station St. Lucia and within walking distance to the Galleria Academia and San Marco as well. A general tip for staying in Venice: you can never go wrong bringing some mosquito spray with you ;)
my friend and I had a wonderful stay in Venice and we can only recommend you to stay at Annas place :)
