Pros (+) Great spot to see Berlin. They weren't kidding about being close to public transportation, and even walking to a lot is a possibility. Room was classy, comfortable and clean. The entire hotel was, to our young eyes, a little classier than we'd normally stay in, but the price was right and we enjoyed it very much.
Cons (-) Took forever to get checked in. Front desk was mostly polite, but we felt a little brushed off waiting to check in. They did however hold our bags as it was well before check in time.
