We had a really good stay in Berlin thanks to Christina! The flat is perfectly placed between the U-Bahn that goes in the center and the Ring Bahn to go anywhere else, the view is magnificent and even it doesn't quite show in the photos the flat is actually pretty big! Christina was very nice and even came to welcome us when we arrive during the night when our flight arrived late. I've stayed in multiple places in Berlin and this is definitely one of the best!
