I stayed here while on a working trip many years ago, when it was a distinctly run-down and gloomy place. But no longer! Having read a few glowing reviews on TA, I decided to give it another go - and I was really glad I did. It's an old brick house set in its own walled garden, in the centre of an old coal-mining town. It must have been the mine-owner's house originally, as it's quite grand.
The bedrooms are all in a new wing that has been built on since my last stay, and are modern, efficient, with minibar, safe, hairdryer, free wifi connection, and plenty of power points.
The evening meal was SUPERB! I stayed on a Sunday night, so feared it might not be great. The set three-course meal (with a choice between two dishes for each course) cost 40 euros, which I thought sounded a lot. But it was of such quality that I would go and stay there again just to have the pleasure of dining there.
The staff were delightful. Someone even carried my suitcase to my room; I can't remember the last time that happened to me!
It's a good place to stay en route to or from Calais, but also for visiting World War I battlefields, and other places of interest. (Modesty forbids me from mentioning a good guidebook!)
