This is a great neighborhood and location. It is on a little back canal and a close walk to water transportation and right near an excellent restaurant. It was hard to find and the directions were a little sparse for someone unfamiliar with its location to be able to get there independently.
I highly recommend it, but the directions are best updated this way: From the airport, take the orange line water transport. Depart Guglie stop. When you get off the dock, look to your right, about a half a block up is the Guglie bridge. Walk towards that (but do not cross it); turn left at the bridge. Walk straight and keep walking. The road will narrow from a very wide, busy street to something half the size. Don't worry, keep going straight. You will cross a small foot bridge. Keep going. When you see the Wind store on your right, which is bright orange, Stop! Turn right at the Wind Store and you will see the Maddelena Church in front of you. Walk on the left side of the church and continue straight through the colonnade arches (you will be passing an excellent restaurant--try it!) until you dead end into a brick wall. Turn right. Walk a few feet and take the first, immediate left. Walk a few more feet and take the first left. You will now be in the correct courtyard.
