You cannot get a better location, there's no way you would get lost. It's a straight path after you get off your stop from the vaporetto. Very close to both the Rialto Bridge and St. Marco square, and a traghetto stop if you wish to cross the canal for just 2euros.
The Jewish Ghetto is also in walking distance and the second day we wandered through streets and found the most amazing antique store!
Paolo was waiting for us outside even though we were running late. The apartment is spacious and we loved the decor! wifi worked great.
I have nothing bad to to say about it, it was the perfect place for me and my sister. If we visit Venice again, we would definitely contact Paolo for sure!
