This place was exactly as advertised, in the best way. It was quiet, secluded, and gave us a chance to hunker down and actually get a good night's sleep–one of the best sleeps we had during our vacation. It's pretty close to the subway lines but we chose to walk to the city center two days, which wasn't a bad walk at all. Kreuzberg itself is interesting and deserves a visit as well since you're already in the area. Overall, can't thank the hosts enough, their guidebook was great and so was communication! 5 stars but I'd give more if I could. Check this place out if you're ever in Berlin. We'll certainly be back.
