The Appartment is very nice and for 4 pers. a perfect sice. We came to Venice especially for the Biennale. The App. is only 5 min. from Giardini and less then 10min. Arsenale away. For Piazza San Marco you can walk within 15 min.
From the App. around the corner you will find a nice street where you find a supermarket and diff. Stores . I warmly recommend this place.
