I stayed in Silke's place with 3 other friends. It was at times a little tight but we certainly managed! The bathroom was VERY spacious, however, and there is enough storage that everyone can unpack their clothes. It was decently close enough to public transportation, and it would'be been nice to have been closer... but it was worth it to be right next to Mauerpark! All in all, a very pleasant trip and a nice place!
