This was my first time using airbnb. Dagmar was wonderful! She picked me up from the airport and was very kind. With her, you're not just renting a room, she opens up her home to you. She answered any questions I had about transportation, Christmas markets, sight seeing, etc. You name it and she'll help you. Also the s-bahn station is within walking distance so it was easy to get around. I can't wait to go back to Berlin. I will definitely be staying with Dagmar again.
