Arianna was so welcoming. She speaks perfect English and lives in the same building. You can ask her all the questions you have, for example she provided us with a city map and we could leave our luggage at the b&b the next day, because our train left in the evening.
The appartement is located lovely, in the quiet and non-touristy district Cannaregio (the ald ghetto), but still only 10min walking time from the central station. The beds were very comfy and the room/bath exceptionally clean.
We could only stay in Venice for 24h, but we ha a great visit with a good night of sleep and when we visit again, we will stay here. See you soon!
