Stop looking and book this place! We got a last minute deal of 50% normal cost, but would have had no hesitation to pay full price. The place is an easy transfer from the airport via the bus to Piazzale Roma and then a quick water bus to the Zattere stop and <100 yard walk to the apartment. The apartment being in Dorsoduro is wonderfully located, a little more quaint than the hustle and bustle of San Marco, and only a brief water bus ride to Rialto/ San Marco areas (stations Zattere & Academia are close). Thomas was a wonderful host making check-in easy and very responsive to messages. Thomas and his wife are picky and meticulous with their property, double checking the apartment was more than satisfactorily clean as we checked in. Furnishings are great and size of the unit is more than reasonable for 2 people. The bed was quite comfortable. We did not use the kitchen, but it was set-up to be functional. Thomas provided solid restaurant recommendations which we took advantage of twice with tasty meals each time. There is a great wine bar (Osteria al Squero) right around the corner with wine 3-5 euro a glass. There are touristy restaurants along the water directly adjacent to the apartment if desired. Check-out was simple as leaving the keys in the door (gate codes protect the courtyard entrance). Thomas allowed us to keep our bags after check-out in the secure hallway of the units while we continued exploring. He was more than willing to help advise you on navigating any transfers to/from.
Overall a wonderful stay and would book again if we return to Venice.
