I definitely recommend Rosa’s apartment, it is just 1-2 minutes walk from the downtown, there is a supermarket almost in the corner and a lot of good restaurants, the place is big enough for 5 persons, ( 2 couples+1) you only have to organize the time to take a shower and that’s it. Rosa was available for all the questions we had and she also helped us to do a reservation in a great restaurant. I will stay again here if I come back to Venice.
