Even though Constantin's place is the middle of Kreuzberg - it is still really quiet and very secure. The apartment is in beautiful old building that overlooks the Spree and the East Side Gallery. The apartment is fully-equipped with a large kitchen. The room itself is very private, and extremely comfortable with a large bed and desk area. Constantin was very helpful and gave me all the privacy I needed, but he was also available for friendly conversation. I loved staying in his beautiful home. Recommended!
