Silvia's place was perfect! In the quieter part of Dorsoduro while still extremely close to the centre. I was there to see the Biennale and it took only 30 minutes to walk to the main venues and the Accademia and Peggy Guggenheim museums are just a couple of minutes walk away. The room itself is cool in the heat, very clean and tidy, and the courtyard nice to relax in after the crowds. Seperate from the main house you could come and go without bothering anyone. Silvia was the perfect host too, very warm and welcoming and easy to communicate with.
Would recommend to any solo traveller.
