Although grammatically correct, it is puzzling to the reader.  Window of your dorm? We cannot deduce from context], I see the port with its ships, the horizon, the cars, people walking by along the sands of the beach's sand and a lot of many hills dotted with colorful houses.  while Santiago is a typical capital.
