Great place. Roomy, clean, classy, 8 minutes to St. Marks square and tragetto stop. I recommend to arrive by tragetto or private bus instead of a 25-30 minute walk thru heavily used streets originating from the Santa Lucia Train Station. There are several foot bridges with stairs to navigate with luggage.
Very nice to have a full apartment to cool off during the busy midday. Venice is best early and late when you can enjoy less tourists and the beautiful refections on abundant canels and views of the sea.
