We (2 adults, 14-year old + dog) stayed for a one-day in Venice experience with simple car-access and guarded parking. All expectations fulfilled. Tiny green for dog next to hotel; larger park within 15 min walk (not nice to walk to). Bus stop <100 meters from hotel; bus 2 Venice every 20 min; about 20 min travel time; 1.50 Euro per person/per ride; 20 Euro buys you a 24 hour ticket incl. Vaporetto boats in Venice (prices summer 2017). Conclusion: location worked as expected.
Hotel: clean, comfortable, friendly personal, good food (breakfast: good, dinner: better, very tasty). Conclusion: much better than "just a stay to get to Venice"!
