We had a wonderful time staying in Jacopo's appartment on Lido. It is just as on the pictures, and it even felt a bit more spacious than we'd thought it would be. The kids (3 and 1) loved the large balcony, and the street and neighbourhood are nice and quiet. It's only a small walk to the beach on one side, and to the boats and the laguna on the other side, and restaurants and supermarkets are close. Jacopo was quick to react and answer the small questions we had. And there's even a small (but growing :-)) collection of kids beach toys, and a baby-chair which can be hung on the table.
We found appartment (and the Lido island) an ideal place to visit Venice with kids: we usually went to Venice or one of the other islands of the laguna in the morning, and then to the beach and/or a small playground in the afternoon. Lido is as easy-going and quiet as Venice is chaotic-touristic and noisy. A perfect home-base to do Venice as a family!
