Grazia's place has an amazing location - one of the best I stayed at in Italy since it is minutes away from San Marco, Ponte Rialto and the Accademia bridge. There are a lot of stairs to climb with some areas a bit tight so you may want to be mindful with luggage and if you have challenges climbing up them. For me, it was worth the tradeoff with a nice balcony view.
One thing to note is that Grazia is very strict on her rules, but is very clear to post them on Airbnb - including prices for late checkin. She was very kind to quickly let me back in the apartment when I was rushing out and grabbed the wrong keys -_-*.
Would stay here again.
