Book without hesitation - it's a perfect place to stay in Venice, totally worth its price. I think the appartment is better than the photos show. Thanks God we booked this appartment and not the tiny room in some hotel near San Marco.
The dining room has two windows and is full of daylight in the morning, the canal is just beneath the windows. You can have breakfast and hear the gondoliers crying "ahoy". Of course, it also means you could hear every boat passing and every suitcase dragged across the canal bridge (and bedroom window has street view with a school nearby so be prepared to be waken up early in the morning on a week day), but we preferred to have an early start for the day before the city is flowded with tourists so it was not a problem.
The dining room also has two couches - great to relax. Very spacious rooms with high ceilings. Shower cabin is not too tiny. Everything was clean and worked perfectly. It's like you have local friends in Venice and are staying in their place while they are away :)
Coop supermarket is just around the corner, it has good selection of local cheese, ham and wine. Rialto market is very close too, we bought fresh fish and vegetables there, then took a traghetto (public gondola) to Ca d'Oro and had self-prepared lunch in the appartment. The kitchen is fully equipped to fry, boil or bake anything. And there is a dishwashing machine and a washing machine.Very convinient to visit Murano, Burano and Lido - the corresponding vaporetto stop is just 7 minutes walk from the appartment. Cannaregio is a nice distrcit, easy to find some "real" Venice and not the crowded tourist streets with doubtful restaurants and made in China souvenirs.
Roberto answered every message very quickly, the appartment is easy to find and we were met upon arrival. Would totally recommend and stay again.
