We couldn't recommend Frank's Flophouse Deluxe more! The pension is comfortable and clean, boasts a quirky decor, and is in a great location - just minutes away from the U-bahn and with plenty of cafés and restaurants within walking distance. Frank was a very welcoming and friendly host and the area of Kreuzberg was one of our favourites - this really felt like a home away from home! We would definitely stay here again.
