Hilton staff were very polite, professional and helpful. We had several 200 Euro bills which they were very happy to break into 50’s and 20’s. The currency exchanges at several airports refused to make change for these bills. The staff also helped us with information regarding the ICE trains. The hotel was safe and quiet and centrally located to multiple attractions (Brandenburg Gate, Museum Island, Fernsehturm, Checkpoint Charlie, etc). Many restaurants and grocery stores within 5 minutes walk. We enjoyed our stay in beautiful Berlin. Highly recommend Hilton Berlin to anyone visiting this great city.
