Appropriately regal and refined, the five-star Otočec Castle Hotel is one of the most atmospheric places to stay in Slovenia, and a member of the prestigious Relais & Chateaux group of luxury hotels. The 10 rooms, decorated in soothing neutrals, come with polished parquet floors, marble-topped tables and large baths, while the suites are suitably huge.
There's a range of packages involving weekends, romance, golf and/or cuisine.
