We had a wonderful stay at Frank's Flophouse Deluxe - Frank was there to welcome us when we arrived and made us feel at home. The decor of the pension is absolutely stunning, and the location is perfect - around the corner from a U-Bahn station, and in a really mixed neighbourhood - so theres lots of different places to eat or get a coffee/ pastries, and it was a great starting point for exploring Berlin. We were looking for somewhere cool that reflected Berlin to use as a base, and the pension is perfect for that - a good night's sleep and lots of free coffee in the morning (thanks, Frank!), plus bedlinen, towels, hairdryer, and a really clean and sparkly shared bathroom. Highly recommended!
