We arrived a couple of hours late but Francine was waiting, with all the doors and windows open. Throughout our stay, she came over every morning to open the pool and have a chat - even though her English is limited, it was easy to communicate.
The house is large but I was disappointed to find a small(ish) shower downstairs and just a 'no solids' electric flush toilet upstairs. There are a couple of sinks up there, too. The shower itself was more than adequate in power and warmth.
The beds were hard (for us), and the furniture in general has seen better days but it's OK. There's a TV and DVD in both the lounge areas, although they're both fed off the same satellite unit (switching channels on one seemed to stop the DVD on the other).
The kitchen lacks prep space but the cooker, coffee machine and kettle all worked fine. I couldn't fathom the microwave and the place needs a baking tray or two. There's also a large fridge with a freezer compartment, plenty of cutlery and crockery, and a selection of pans.
We drove to La Coupole (inc 3D planetarium), Le Touquet, Agincourt visitors centre, and some of the local towns. There is a supermarket, café, and petrol station in Anvin, a couple of kilometres away. Otherwise, you're fairly remote - it's very quiet except for the occasional tractor, birdsong, and a crowing cockerel.
The pool is covered, heated, and not too deep. Our 11yo was in there for 2-3 hours almost every day.
All in all, a peaceful, relaxed time.
