10/10 would recommend
Julia's flat is perfectly situated in Prenzlauer Berg - which is a great neighbourhood for exploring flea markets, great restaurants and cafes (try Bonanza Coffee Heroes across the street), even better shopping (included 5 record shops within walking distance) combined with the history and memorials of the GDR and Berlin Wall.
The U Bahn and Tram are just around the corner and make getting into central Berlin very easy.
The flat was tidy and full of quirky personal art and flair.
Julia was greatly hospitable and greeted us at the door even though we were late. She communicated with us throughout and provided anything that we needed.
Just be prepared for 5 flights of stairs, I promise the apartment at the top is worth it though!
