Stayed here for two night in connection with Berlin Marathon. Located in heart of Berlin on the calm Charlottenstrasse close to Friedrichstrasse and the marathon start it was a perfect base for the weekend. Fantastic service and welcome in the reception and the breakfast buffet was second to none. Very spacious rooms (well, we were two marathon runners in a suite that easily fit one extra bed) of very high standard. The spa was nice after the race, although a whirlpool or swimming pool wouldn't have hurt. I would definitely come here again.
