Review in a few words: This is a truly wonderful hotel that can absolutely compete with five star luxury alternatives.
Review in full: We stayed at this hotel for the Berlin marathon and we were blown away by the quality of our room and level of service provided by the staff. This being our first times to Europe, we didn't quite have our sea legs and the staff at check-in were patient and helpful with all of our questions about the area. They really went above and beyond to ensure that we were set and settled.
We received a small room upgrade (Deluxe to Superior) as a part of our Marriott status and were completely impressed. The room was spacious and beautiful. The beauty of the room is punctuated by ENORMOUS windows that really impress. While not a Suite, we didn't really want for much if anything in this room and we were blown away by the level of quality.
We had made our booking with points, so breakfast was not included, but we tried it out all the same. The hotel does a great job at providing a wide array of buffet options and I would absolutely recommend giving it a try if you convenience is a factor in your morning plans.
I must take the opportunity to praise the staff again as they were constantly helpful throughout the duration of our stay. They even went out of their way to write a nice congratulations card following the marathon and gave me a few necessary token gifts (sports drinks and food). It was a really small but really nice gesture.
We cannot wait to get back to Berlin and there is no question that we will be staying at the Hotel am Steinplatz again. What a fantastic stay!
