Very handy for a family party at the nearby (and excellent) Trafalgar Tavern.
As you can see in the photos, it's a spiral staircase, but it is very narrow and if you're less than fully mobile and/or average build, you will struggle. Parking's a bugger with narrow streets and residents-only bays, though a permit can be arranged in advance.
I'd stay there again because the location is convenient and better value than nearby hotels.
