I have stayed at this hotel numerous times in the past 10 years or so and it never disappoints. The service is consistently good, staff are friendly and helpful and the amenities excellent. The food is always of very high quality and the bar is comfortable and relaxing after a hard day.
A recommendation - book a 'Comfort Plus' room, overlooking the gardens, these rooms are far quieter than the rooms at the front of the hotel that although soundproofed, are overlooking the Autobahn.
