The flat is really well placed in the main center of Venice, 3mn walking from piazza San Marco. With a nice balcony over the other buildings which is really nice if you want to have a drink in the evening or a coffee in the morning.
Roberta and Alessandro have been helpful in communicating beforehand and it was easy to meet to get the keys.
One only thing, the stairs are quite stiff to get to the 5th floor.
