Christel is a wonderful host. The description to arrive at her place is very precise and you can't get lost. The place is idealy situated. It's not in the center, it's in a cute and quiet neighborhood but it's 10 minutes from the old city with the Ubahn, which is at 2 minutes of the house. There is en Edeka and an Apothek at 10 minutes walk from the house. I really enjoyed my stay there. Everything was really easy.
And last but not least, Christel is a very nice person. We didn't get the chance to talk that much but she is very interesting.
