Couldn't recommend this apartment more. The location is ideal- a few minutes walking distance from St Mark's Square and the Rialto, but just secluded enough that you feel like a local. The apartment itself is very clean and comfortable, and bigger than it appears online. The living room in particular is very spacious with a large table/chairs and a big comfortable couch, so I imagine it would be ideal for longer stays too. Francesco was quick to communicate and always really friendly. He even let us keep our bags in the apartment after check-out which was really helpful. All in all, we have nothing but good things to say.
Tip: there's a really lovely café in the square around the corner with fantastic coffee and croissants.
