Gunter was a great host. He was very helpful from the start - sent us detailed directions to the apartment well in advance of our trip. While we didn't meet Gunter, his daughter Hannah lived nearby and she was very easy to communicate with. She was very friendly and gave us the keys and a few great tips about the neighborhood! The apartment was lovely - just as described, clean, comfortable and great location along the canal. I would highly recommend this apartment for your trip to Berlin!
