My stay at Mauro's was great. There is a bus stop just a 2 minute walk from their place which will take you straight into the central bus station in Venice. This is about a 20 minute bus ride. Buses run quite frequently as well. They have a cute little dog called Lula and Marli prepares a wonderful breakfast spread for you as well. There are a few flights of stairs to climb so if you have a big bag it's a bit of work! Other than that they are a lovely host with lots of ideas to share with you about Venice. I'd stay again!
