We found in Cavallino Treporti a really nice flat nearby the beach. It takes about 3 minutes to walk to the nice sand beach. There are three private beaches for two camping areas and a hotel, and a moderate size public beach. As we stayed there in mid- September, there was almost no one at the beach.
The flat is spacious and well-equipped, so we didn’t have to think about any routine issues. There is a plenty of dishes, pots, a frying pan, bed linen and towels, A/C, a washing machine and even a beach bag. The flat owner was very friendly. The area around the flat was really calm and quite, almost no traffic, only a few campers leaving. There are no bars or supermarkets in walking distance, only a pizza restaurant at one of the camping areas. We would recommend to stay in this flat only when you have a car available, because grocery stores are about 3 - 5 km away. Parking the car is very convenient, there is a private parking spot on the territory of the house.
All in all, we would recommend the flat to everyone who wants a calm and relaxed stay close to the beach.
