We (a group of 5 friends) had a pleasant stay at Sabrina's apartment. The location is great, we could walk everywhere. The apartment is bright, spacious and clean. It had everything we needed. The only thing that Sabrina could consider is to leave some basics like tea, coffee, salt and oil in the kitchen - the kind of things that you don't buy for a weekend but really appreciate when you need them.
The apartment is a bit hidden in a narrow, little side street, but was not difficult to find thanks to the instructions we got at the check in and google maps.
I'm happy to recommend Sabrina's place for a holiday in Venice.
