Stayed there 3 nights for business/leisure. Staff is very friendly and take time with you. We had a superior room, very spacious, nicely decorated, with revolving fireplace. The pool is underground along the spa and small fitness room. Restaurant is upscale/pricey but delicious (count €50 for menu),with good wines. They had a Michelin star in 2007. Please try the bar, it's very cosy and modernly decorated. Breakfast is simple but complete.
You are walking distance to the dunes and village center where you can rent bikes, restaurants, shops, etc
