The apartment itself was in the absolute perfect location. A short walk from San Marco and Ponte Di Rialto. It was small, but beautifully decorated and clean. The beds were a little uncomfortable, but it wasn't a big deal. The rooftop terrace was unbelievably beautiful and quiet (especially considering how many people are in the city). We enjoyed sitting out there every morning and evening before bed.
However the check in process was a real pain. As instructed, 30 minutes prior to our arrival, we called the phone number that we were given and then told a man (some sort of associate of the host) would meet us to let us into the apartment. Shortly after, he then told us that he was busy and another woman would meet us instead to let us in. We ended up sitting in an alley waiting for over an hour for the lady to come let us in. In the grand scheme of things, it was just a minor inconvenience, but seeing as they already knew in advance what time we would be arriving, this shouldn't have happened.
Overall, it was a nice apartment in a great location. I would suggest working on the check in process and making sure that doesn't happen again to other guests in the future.
