Hotel Cipriani
Set on Giudecca Island, five minutes from San Marco by private launch — genuinely away from the day-tripper crowds, and home to Venice's only Olympic-sized pool.

Late April–May or October — the same canal grandeur with a fraction of the cruise-ship crowds of June through August.
Crowd hack
Stay on Giudecca rather than in San Marco proper; the private launch means you skip the pedestrian bottlenecks entirely.
Insider tip
Visit St Mark's Square before 8 AM — the private launch can drop you there well before the day-tripper ferries arrive.
