Location: close to all main tourist attractions in Venice, few minutes to St Marco Square, overlooks one of main walking paths - Riva Degli Schiavoni. Also close to water transport stops - makes travel around Venice and lagoon (Murano, Burano, Lido and others) easy. Good public water transport from railway station and airport for those who want to save on water taxi. Hotel's own water taxi and gondola stop.
Rooms: nice, cozy, quite big as for European city, very clean and well maintained. Also suites, last year we booked one with private balcony. This year we booked double overlooking St Marco basin. Large terrace on the top floor, excellent to watch the basin, Island of S.Giorgio Maggiore, very busy water path, sometimes with big ships, and entrance to the Great Canal.
Services: solid breakfast with good choice of food. Own restaurant open at the evening. Bar - serves also appetizers before restaurant is open. No concierge but the front desk staff great and friendly, they are always ready to give you advice and help to set things. We followed their recommendations several times and we were never disappointed. Staff really makes a difference here.
General: small hotel which gives you all you need plus family feeling and individual treatment. Instead of recommendation I can only say that this was our third stay at Locanda Vivaldi and we intend to be beck next year to this place.
