Me and my husband enjoyed very much our stay at Sarah's home. The location is perfect since its near by the San Marco square. My favorite thing was to listen the bells from the churches in the morning. It really gives you that Venetian feel. The apartment also has different beautiful views of Venice from their windows. Be aware that you have to climb 90 steps to get to her apartment, my advice is to bring small suitcases.
The host provides you a rule book about the house rules and insights of "to do and what NOT to do" in Venice which was excellent because we wanted to explore as much as we could by not doing the same thing everybody else does while touring in Venice. The kitchen area is also filled with all kinds brochures of information about what to do or where to go in Venice, which was very helpful. We already came prepared because the host sent us all sorts of information through inbox. She also has a guest book where you can leave a thank you message and the country where you from, which I think It was a cute idea.
Overall, we loved it and we would totally stay again at Sarah's place if we come back.
