The apartment is very clean, spacious and stylish. You have everything you need and the highlight definitely is the big rooftop terrace, where you can enjoy a glass of wine in the evening with an amazing view. If you're lucky, the restaurant nearby has some live-music too ;)
Elena was very friendly, everything was as told and the check-in and out was very easy.
The jewish ghetto Cannaregio is my favorite area in touristic and crowded Venezia, just talk a walk through the small canals in the evening and head up north, where you can still meet locals and find good food in affordable restaurants. I highly recommend the Kosher Restaurant Gam Gam! And go to Biennale!!!
Definitely will come back. Greetings from Austria
