Elena's apartment is super nice. Very spacious, very well-equipped in a nice modern style. Everything is like as shown on the pictures.
Dorsoduro is very quiet, but only a few steps away from the more lively areas. Piazzale Roma is in walking distance (15 mins). Also Vaporetto stops S. Basilio, S. Marta and Zattere are quite close.
Elena is a wonderful host. She picked us up at the bus stop during the night (!) and led us to the apartment, provided us with useful information and responded instantly to all questions. She speaks English fluently which was very helpful for us.
