If you are staying in Venice and wish to avoid the more touristy and expensive areas, along with the accompanying noise, Lido is an under-appreciated gem. Trendier and more residential than traditional Venice, it still offers small canals, a variety of dining and impressive views of the city from across the Lagoon.
Villa Gabriella Dimora Storica Liberty is a part of a villa built in 1922. The design was inspired to the Palladio's Rotonda. Located in the Lido Island (Lido di Venezia is Blue Flag for sea water since 2008!), in front of the Adriatic Sea, it's 20 minutes far from S. Mark Sq. Wonderful panoramic seafront terrace. Last complete restoration: 2010!
Gracious, 4-star country house hotel, 5 minutes walk from the beach and 15 minutes by Vaporetto to St Marks Square. The spacious rooms are all air-conditioned, there's lovely floral gardens and a large outdoor terrace where you can eat in the shade of a huge, ancient plane tree.
