This is right in the heart of the San Marco area, so you need to be ready to find a route that avoids the crowds before you head out. There are tons of people around in the summer, and Bar Bra across the street is a bit noisy, but the location is very central and you can get over the noise quickly with a white noise app on your phone :)
Stefano was very nice and helpful and the terrace is secluded and pretty.
