Even though the apartment is a little removed from the center of action in San Marco or even around Rialto, a water bus gets you to either place in 30 minutes or less. Moreover, there is a piazza nearby with restaurants and a grocery stores. There are also gondolas to rent nearby. The area (San Croce) is also quiet and peaceful. The water bus stop (Line 1) is a short walk from the apartment (less than 5 min).
The apartment may have dated decor but it is cozy, clean, spacious and has a lot of amenities. Mario and his staff are responsive and helpful.
My family and I enjoyed the night we spent there.
