This was a cosy apartment on the first floor - the door of your apartment opens directly onto the Grande Canal - so you will have a lovely experience of the Grande Canal.
There is a kitchenette with absolutely everything you will need: cups, plates, silverware, and even pots and pans if you need them. There's also a kettle and plenty of tea sachets to enjoy. There were various other food and drink items which Cristina was kind enough to provide.
As for the location- we found it quite suitable for accessing all the main points of interest; Piazza San Marco is a quick vaporetto ride across the canal and only a few minutes walk from Piazza San Marco is the Ponte Rialto.
The apartment is equipped with an air conditioner unit - but after our first day it had stopped working (or perhaps we couldn't figure out how to get it started up again?). But it wasn't so bad for us as there's a fan that works well.
Overall i would say that this is a good place to call your base as you explore Venice. And you will find Cristina and the other attendants quite easy to deal with - our interaction with them was minimal and everything ran smoothly. I would recommend this apartment as well as Cristina should you be in Venice.
