Apartment five was a really lovely place to stay - lots of windows, very high ceilings. You can even glimpse the sea through the trees from the vast master bedroom. The second bedroom is very small, but the size of the living/dining room (bigger than we expected) and the main bedroom (with its large desk in a curtained study nook) makes up for that.
Not a particularly soundproof place (as you might expect from its heritage status) but the traffic noise didn't bother us and thanks to the thick carpeting (and everyone removing shoes upon entering) not much noise leaked in from the stairs or landings either.
The cooking facilities are pretty basic - just an electric pan, plus kettle, microwave and toaster. You do have to provide your own cooking oil. There was an ironing board and iron in the room though which was nice, and the communal laundry facilities were easy to use.
Basically, I thoroughly recommend this place- as long as you're comfortable going up stairs in bare feet or the provided slippers!
