Although this hotel markets itself through the Gast im Schloss consortium, first impressions are not so much of a castle as of a town hall - no surprise to German-speakers, who will know that its name translates roughly as 'Princely Official House'. But it has the impressive hilltop position and long views (enjoyable from the terrace) of a once-important fortress, and public areas full of grand antique furniture and an interesting collection of clocks. Gunter Probst enjoys publicity, and one of his many special leaflets promotes his star possession, the 'Best-known bed in Germany', slept in by over 50 visiting heads of state when it was in government accommodation in Bonn (it was lengthened for De Gaulle, strengthened for Brezhnev). The Graf Leopold restaurant is an atmospheric setting for the 'new German cuisine with an Italian tendency', which is competently executed and supported by an excellent wine list. There is an attractive heated indoor swimming pool, hewn from volcanic rocks.
