We went a week there and knowing very well how things work in Italy, let me tell you that place is well maintained with a good isolation and a central heater very efficient. Indeed, we went in October and during the night which was cold, only half hours to have the entire place comfy for the rest of the night.
Moreover, extra comforters were available and beds have good mattresses. Bed sheets and bath towels as well were clean.
Equally important, the kitchen, if you like to cook time to time "un buon piatto di pasta fresca" you will find all the utensils, even the wine glasses that you need to eat like an Italian ;)
In addition, if location means something to you then that's the place to be. First of all, you are next to a marketplace called Coop with all what you need to enjoy a nice dinner at home without having to carry your grocery shopping by narrow streets and a compact crowd. Furthermore, you'll be at 5 minutes from Rialto bridge and Piazza San Marco as well.
Finally, I had some requests to Luca, he always answered quickly and kindly. Everything has been thought to give you a good experience in this mysterious and so unique city. Even the hostess who will pick you up at the Vaporetto stop to guide you to the apartment whatever the time you will arrive.
Enjoy as we did!
