One of the best apartments I've ever stayed! If you like it on photos, believe me, it's even better in reality! I call places like this - a place of 1001 details, as everything is set up just perfectly.
What I liked most of all is the location. It's just lovely, surrounded with a lot of nice art galleries, cafes..! So peaceful, charming, you cannot not fall in love with this place! Literally! If you hesitate where to stay - on the island or land, please do not hesitate - stay on the island!! You come to the city to explore it, so don't waste your time on traveling there at least twice a day! Be lost in the city, enjoy its canals, turns, and millions of little bridges. It worths extra money you pay for the place to live on the island!
The apartment is close to everything - 4min to Gallerie dell'Accademia (for more classy people, I I really liked this museum btw), 5 min to Collezione Peggy Guggenheim (it has mostly modern artworks), 20-25min walking through Piazza San Marco to Venice Biennale in a lovely garden (great decision to hide there in a hot day btw;), and 17-20min to railway station.
And I must say a few words of the host! Luca is so welcoming, open-minded, and nice person! To tell the truth I have always thought that Venetian people hate tourists as there are tons of them, but it seems that Luca loves the city, and enjoys sharing his feelings and knowledges of it to people he welcomes in his home. He provided us with even more than enough information we could ever get from any guide books or internet. He is a real example of the super host.
So I highly recommend this place!
