The apartment is in a perfect part of Venice as far as we were concerned. Only ten minute walk to the Rialto and just three minutes to one of the main vaporetto stops at Fondamente Nove. Yes the apartment is on the third floor and we had to get our suitcases up the stairs, but it was well worth it. The apartment was spotlessly clean, and the fridge, freezer, washing machine, gas bob, kettle, microwave etc are all as good as new. Wi-Fi had a good signal and the air conditioning in the bedroom was a real bonus especially as we were in Venice during a hot few June days. The views from the apartment were joyful and it was lovely to wake up and throw open the windows to enjoy the sound and sights of the Venice Canal below. Cristina was also an excellent communicator and we had confidence from day one that the trip was going to be smooth. There are plenty of good restaurants within a few minutes walk and we used Trip Advisor to identify the best.
We were in Venice for three days and it was worth buying the 72 hr Vaporetto pass at €40 pp, which allows unlimited use and was useful for getting from one side of the city to another as well as getting to the islands of Burano, Murano and Mazzorbo. The nearby Fondamente Nove stop was on the right side of Venice to access the islands and also was the perfect starting point to get to the airport. Note if you have a 24, 48 or 72 hr Vaporetto pass then the cheapest way to the airport from Venice is to go to Morano ( the Colonna stop) and then buy a separate ticket for €8 to get the Alilaguna service from the same Morano Colonna stop to the airport.
