Though not on a canal, it is a building with a large inner courtyard: our windows overlook the courtyard.
The entrance to the inner courtyard.
Either side of the courtyard, as soon as you enter.
Lots of long, narrow, stairs. The view from one of the lower floors.
My 'room' is a loft perched above the living room/kitchen/dining room. This is the view down all of the stairs from my nest.
