Bernd and Katja's apartment is a little jewel tucked in a wonderful neighborhood. The apartment is warm and welcoming and has every convenience a visitor could want. The place is clean, colorful, and set in a nice old building with a beautiful courtyard. Katja and Bernd are kind and welcoming and see to a visitor's every need. Their communications before I arrived were so helpful and their support while I was in Berlin was very helpful. I loved my stay in their place. I will be back!
