My friend and I stayed at this apartment (Interflat 3) for 6 nights. The apartment is located on the second floor, facing an interior courtyard on a very small side street. It is very quiet, close to Piazza San Marco and the photos are accurate. We had trouble finding the apartment (which is at 5335 Casseleria) even with our iPhone GPS but we were met on the street by Marina and shown to the apartment. The major drawback is the sofabed, which is barely useful for sitting and not comfortable for an adult to sleep on at all, with just a 2 inch piece of foam on top of the wooden slats (this is an Ikea folding "sofa" bed). The living room also holds the dining table, so with the sofabed opened there is not a lot of room left. Despite this we enjoyed our stay - the owners were very responsive and the apartment was well equipped for basic cooking and had excellent water pressure. I'm not familiar with accommodation prices in Venice, but $150 a night seemed a bit pricy - although we discovered that Venice is quite expensive in general.
