Aurelia’s place is a very easy 10 mins walk from Venice (Saint Lucia) train station-- if you travel light (like we did). It’s in San Polo, which is less crowded than San Marco and is an easy walk to all the ‘must visit’ places in San Marco. La Zucca (vegetarian) and Barraria are two great places for a meal, both are less than 10 mins walk from the house. Both may need a reservation.
The house is on 3rd floor, which will be an issue if you have luggage.
Aurelia personally attends to guests when they arrive, which is a great gesture. She also offers good ‘starter’ advice on how to go about exploring Venice.
