We let out a lovely spacious barn conversion on the Pembrokeshire coast. A bit more than 3 hours from London, but well worth the extra drive. We can't offer you an indoor pool, but we can offer you log burning fires, fantastic views from the living room and master bedroom, and lots of children's games, toys and videos to keep them entertained while you attempt to have a lie in. I can offer you a special rate for the first weekend of Feb of £295 for 3 nights (it's booked 9th Feb). Checkout www.cilcainmathry.co.uk
