What an amazing place, with such character and such a lovely owner. Frank is a really welcoming and helpful host who keeps the place spotless. It's very centrally located for all the bars, restaurants and pubs around Kreuzberg - so you're in the thick of it, but only a short metro ride away from the touristy areas. The room is not the most sound proofed room, so you do hear the neighbours now and again - but that was completely fine for me. The room itself is a work of art with gold curtains and surprises all over the walls - feels like being part of the art to sleep in it! I'll definitely stay here next time I'm back in Berlin.
