Federica offers excellent communication, a very central & nice flat, and overall kindness and professionalism.
If you are going to Arsenals or/and Giardini for the Bienalle, the flat is ideally located. It's also ideally connected to several vaperetti lines.
The flat itself has all the basics needed, is very clean, has nice south light, and was very quiet for sleeping. Wifi was also fully functioning.
If you will visit Venezia, I can warmly recommend Federica's air bnb for a pleasant stay.
