My stay at The Movenpeck hotel was absolutely brilliant, staff are the most polite, courteous, helpful and professional people I have met in a long time. Overall service was just second to none. would definitely recommend this hotel.
Stayed at the Radisson for 4 nights in October. The staff were very friendly, the concierge was helpful. We stayed in an inside room, didn't have any blue light at all that other reviewers have mentioned. In fact it was very quiet. The hotel is in a good location just down from Alexanderplatz and within walking distance of Brandenburg Gate. I didn't have the breakfast so can't comment on that, but would definitely stay there again.
Me and a friend stayed in a spacious twin room. It was spotlessly clean and nicely decorated. We had a very comfortable bed, air conditioning, phone access, tv, spa and gym facilities (unfortunately no pool but we already knew that before arrival). Restaurant and room service available. Beautiful bathroom, dressing gowns and slippers, everything we needed. The staff were very welcoming and helpful. I had never been to Berlin before and neither of us spoke German so this was particularly useful. Perfect for a city break.
