Marta's apartment is a great place at a fine location, close to the big Excelsior hotel, public transport (bus; 4 stops to Lido SME) and some shops and restaurants. Also the beach is closely.
It seems to be the ideal location when you are attending the film festival; we used it for the Biennale.
Very comfortable, with a large living room, balcony, 3 bedrooms (two larger ones and one with two separate beds) and 2 bathrooms (one small and one larger). Funny that you enter the apartment in the kitchen; some American than Italian ;-)
We certainly recommend Marta's home.
