We stayed at the Ritz for several days and enjoyed all of the amenities. The buffet-style breakfast was delicious but pricey. The rooms were of course spotless and beautiful. The front desk staff was courteous and the concierge desk was very helpful but not overly friendly. I had to use the business center a lot, it was pretty expensive but once in a while you could use the internet with out a code. The location was perfect! Very close to the train station (Hauptbahnhof) and a nice walk to pieces of the wall and to the Brandenburg Gate and a short cab ride to the Kurfurstendamm. Would highly reccommend.
