I went on a trip with my mother. What attracted me to Mario's listing was his apartments close proximity to the waterbus. It was a quick walk (about 7 minutes), which was important to us as my mother cannot walk for long periods of time. Though everything in Venice is walking distance away, being close to public transportation was important to us since my mother cannot walk very far. We bought a unlimited pass for the water bus (about 21 Euros) which ended up being very cost effective since taking one ride was 7 Euros. The pass allowed us to easily travel around Venice and even to Burano and Murano. I would recommend this to anyone. The apartment was very clean. It was very hot but Marios apartment had a little fan that helped. The apartment was a little difficult to find so be sure to download and offline map just in case you do not have service. When we checked in the apartments Wifi did not work. I contacted Mario about the issue and he got back to me a day after (by that time half of our trip was already done). Other than that it was a perfect stay and I would definitely go back if he will have us.
