Super quick communication and great location! Beatrice was a wonderful host, and suggested a great restaurant nearby (Casa Bonita). There is a supermarket a short walk away if you follow the street and passageway down from the apartment.
To get there from the airport take the orange line ferry to Guglie and the apartment is across the canal (you will have to cross a smallish bridge to get to the other side). Walkable from the train station if you don’t have too much luggage, otherwise you can take the water bus to Guglie or Crea. If headed to the bus terminal area to rent a car, take the water bus from Crea to Piazalle Roma to avoid dragging your luggage there and over bridges.
