The flat is located a 3-minute walk from Santa Lucia station, which was perfect as we arrived by train. Closeby, you'll find countless nice restaurants and cafés, there is also a supermarket next door. The area is way less crowded and touristy than the area around Rialto and S. Marco, so even though it takes a bit longer to get to certain places (most of them still in walkable distance, though), I'd definitely recommend Santa Croce.
The flat itself is very spacious and beautiful, overlooking a canal. It is equipped with everything you need, even a dishwasher, even though we'd have wished for some more supplies like soap. The water pressure in the fixed shower head is unfortunately almost nonexistent, so you have to do with the hand-held shower head instead.
Arianna and her colleagues were AMAZING during the whole process. They gave us a lot of information on the check-in process, how to get there from various arrival points etc. Thanks to the very detailled instructions, self-check-in was no problem at all. I never had such great communication with an Airbnb host before!
