Venice, Italy, known as Venezia in Italia, is in the region of Veneto on the Adriatic Sea. "La Serenissima," the Peaceful Lady, was home and harbor to international commerce, and did not need to fortify itself much against attacks. Its architecture features airy terraces, balconies, and huge windows, letting in the most possible light and ventilation, and stands in sharp contract to cities such as Florence (Firenze), in Tuscany, whose palaces had to be sturdy, impenetrable fortresses.
The actual first settlements in Venice were out in the Lagoon, on islands such as Burano and Torcello. The "mainland" was marshy, its brackish waters unhealthy (and building there was an engineering challenge). When plague set in, however, long ago, the inhabitants abandoned the islands of the Lagoon, and did settle inland, with difficulty, but tenacity.
The Guidecca is a large island near central Venice. Mostly residential but a quick bus-boat ("vaporetto") ride to and from the center of Venice, it's considered by some to be a more "authentic" Venetian place to stay. It certain commands gorgeous views! Hotels in Venice come in all shapes and sizes.
