London and it’s boroughs abound with squares. We stayed in a lovely bed & breakfast in Norfolk Square (easy walking distance from Paddington Station).
The window to our room at the B&B from the outside (in Norfolk Square).
I’m not sure if this is an unusual point of view, as thousands of people walk past the front of Westminster Abbey in London each month (possibly each day), but I don’t know how many take the time to look up.
