I've visited Venice many times and Ernesto's apartment is one of the best places that I've stayed.
The apartment is spacious, clean, comfortable and incredibly well equipped. Great if you want to cook. Ernesto had left a great selection of supplies, including a very welcome bottle of prosecco and all the ingredients for a Spritz.
The location is ideal. Very quiet with views over a canal, yet really near lots of great local restaurants/bars and a good supermarket. Also very handy for Vaparetto stop, especially handy with luggage as no bridges involved.
Ernesto was a great host, very welcoming and informative, with immediate responses to all communication right from the time of booking.
