Giulia is very quick at helping us figure things out. When we had problems with the heater, she rectified it in only a few hours. Her apartment is fairly accessible from Marco Polo by bus without much walking and her instructions were clear enough.
Getting to and from Venice was easy; we just have to take bus 24 and it's fairly quick at about 15 minutes. This bus stop is about 3-4 minutes away and pretty accessible but also far enough to dissuade you from going back to take something you've forgotten from the apartment.
The ambient sound was ok, with audible road noise and sound of neighbours walking above the apartment but it was very much ok.
The floor tiles of both the apartment and the toilet were very cold to touch and it was not too comfortable getting around. The amenities however was good with a good set of kitchen tools and appliances. There's a hypermart nearby (2-3 stops away) too.
Overall, it is of great value if you are able to live with the mentioned trade-offs.
