The balcony view of the park and the Rhine valley stretching all the way to the Black Forest is sensational. The two-floor Castillo Alcazar rooftop hotel bar featuring a gallery makes guests feel like they are in a medieval castle thanks all to its labyrinthine rooms, balustrades, coffered ceiling, wooden horses, riding saddles, coats of arms and knightly armour. Up high in the battlements on the ninth floor of the Castillo Alcazar, the sophisticated Buena Vista Club bar, its open fireplace and decorative library are reminiscent of the world’s most famous Spanish-speaking band: the singing señors from Cuba. There’s something to discover in every corner, along with first-class mixed drinks.
