Ralph was very accommodating in meeting us at the place, and the house was immaculate. Definitely an exciting place to stay in Berlin - very easy to get to lots of cool bars in Kreuzberg and Freiderichshein and a nice, relatively short walk to Checkpoint Charlie etc. There's an amazing new bar a couple of doors down called Black Sugar International. We went every night and Edwin (the owner) made us feel totally welcome! We were pulling our own drinks by the end of it. Can't recommend the apartment enough.
