5 of us spent the week before Christmas at the Moorings and had a lovely stay. The house is really large, modern, tastefully decorated and well kitted-out. Location is ideal - It's very close to the town centre and tucked away in a cul-de-sac but has parking for two cars. Great starting point for several long walks, and Wells is lovely - the sandy beach is enormous and pretty with the beach huts, and plenty else to do (e.g. Walsingham mini railway in season, whisky distillery, great restaurants)
Would definitely recommend and go back.
If there was anything to change, I'd only point to the entry /exit times which felt a bit late to be getting in on the first day and a bit rushed on the last, but that's a minor point.
