Nell Gwynn accommodation is a professionally-run hotel-style block of apartments. It was quiet, in a lovely area, and exactly as described. I would certainly recommend it to anyone who doesn't want a proper "host" in the background, and who wants that hotel style. I didn't encounter any Londoners, but that was fine on this occasion. Nice staff, neighbours were other tourists. I liked the 1930s "Poirot" style of the building, carried through in the decor.
