The stay was great in Venice for a very affordable price. The location was about a 15 min walk from all the big touristy sites in Venice but it was nice to do that walk and explore the little alleys and bridges in Venice. The area is quite local with some small businesses downstairs but nothing too noisy once they close up for the day and we were back resting in the apartment.
For the apartment itself, everything that was presented was what was listed in the airbnb page. There's no wifi but the 4G signal is decent for messaging and using social media. Also note that no toiletries are provided (except towels), so you should bring your own but there are also many supermarkets that you can buy toiletries from nearby.
The only issue we had was that we had some difficulty in opening the main door, but that could have been our own stupidity as well. After a kind person taught us how to open the door, it was all good from there!
Overall, great stay at Mario's place and would recommend for a nice budget option in the heart of Venice.
