The apartment was as described; from the parking lot (Tronchetto) it was easy and convenient to reach by Vaporetto. We were met (as agreed) by Enrico, who was very helpful and friendly. The roof top terrace was brilliant, equipped with everything needed incl. an electric awning The only thing that you should be aware of is that the windows do not have any fly screens, so you might want to bring some Autan.
The apartment's location is very central, with just a few minutes away from the San Marc's square, and not too far away from Rialto. Bakery, coffee bars, supermarkets and restaurants all close by. Would recommend the apartments.
