We loved to stay in Elisabetta's apartment. Especially to location, with everything within walking distance, is great. We recommand to take the Alilaguna boat (Blue Line) from Aeroporto Marco Polo to Fondamente Nove. From there it is only a five minute walk tot the apartment. Going back to the airport from Fondamente Nove is tricky, for there is a big chance that the boat is already full at arrival. Walking to Piazzale Roma (35-40 minutes) gives you lots of oportunities (ATVO fast bus 25 minutes) and assurance to get to the airport in time.
