In the top photo, the Santa Lucia Railroad Station
is on the left, the Scalzi Church is next to it, and the Rio Terà
Lista di Spagna is just past the
Ponte dei Scalzi
bridge. The Hotel Principe faces the Grand Canal near the right side
of the picture, just before the open area along the waterfront.
In the second photo, you can see the front building
of the Hotel Principe (where the entrance is located) near the lower
left corner of the frame.
