Abbaye des Vaux De Cernay

A medieval abbey turned country-house hotel about an hour from Paris, where the Rothschild family's old hunting lodge is now one of several restaurants, because the group behind this place made its name feeding people before it ever put anyone to bed. Rooms spread across the original abbey, reconditioned stables, and freestanding pavilions. There's a spa, a cinema, tennis courts, boats on the lake, and enough parkland to get genuinely lost in.
