I had some minor initial reservations due to the physical distance from the Hbf and the main train station but they were quickly dispelled once I learned how easy if was to use the subway. Via subway, we were mere minutes away from the city center and all the attractions for which we had interest. Don't be afraid of the subway--it's VERY easy to use and inexpensive. Katerina and Bernd were very easy with which to communicate always promptly returning emails or text messages regardless of the subject. Katerina even offered sage advice on nearby architecture and aspects of the german language! Another plus was the individual arrangement of an initial taxi from the train station to the flat. Our driver parked outside the station and was waiting for us at the bottom of our platform staircase. Wow! The flat was impeccably clean and well furnished. Pay attention when being taught how to turn on and tune the TV if you wish to watch it. We loved the place and would definitely return.
