I stayed at this hotel a number of times in the last 15 years, it was a really great place to stay and was my favorite hotel in Berlin, verging on 5 star luxury with a great spa, excellent service and an amazing breakfast buffet, sadly it was gone down hill, the spa was unkept, the breakfast buffet was basic and the hotel is looking worn. While I would say my stay was not terrible I felt disappointed that place now has the feel of a 2 star hotel.
