Perfect location in Venice if you come by train to St. Lucia. And there is also a direct bus to the airport near by.
Directly located at the grand canal you can use different lines of vaporettos.
And if you are lost in the small streets and canals of Venice you can always find your way back looking for the "ferrovia" signs.
Nice and clean little appartment with the main facilities in place (small fridge, coffee making machine etc.)
Communication with the host was perfect. Quick reactions and fast check-in.
Good choice!
