The apartment was nice with comfortable beds. The shower was tiny and uncomfortable but the water was hot, so it was manageable. The location is perfect, just a short walk to Piazza San Marcos. And that walk to get there is beautiful, walking through a wide cobblestoned neighborhood walkway (no cars of course) with kids & dogs playing and shops & restaurants along either side, then arriving at the picturesque seaside where St. Mark's is only a few bridges away. Experiencing that neighborhood really enhanced our experience of Venice.
Check-in was kind of confusing. We were buzzed into the front gate but didn't realize that this also unlocked the door to the building, so we stood confused for awhile in the courtyard waiting for our host to come downstairs to escort us to the room. Eventually we got into the building, but didn't know which floor our room was until we wandered up a few flights and saw our host waiting for us behind an open door. It would have been so much easier if our host had simply walked downstairs to meet us. There was also a local tax (3 Euro per person, per night) that we were asked to pay upon check-out. I feel that all costs should have either been included in the amount we paid to AirBnB or at least disclosed in the advertisement. But these are relatively minor inconveniences, and overall we would definitely recommend this apartment.
