Baerbel was helpful and communicative. She gave us a lot of tips at check-in and answered all our questions along the way. The place was spacious and well-equipped. The location was also good: very close to the U-Bahn (a couple blocks), just a few blocks away from a grocery store, and right around the corner from a pizza/pasta/burger place. We stayed three months and were able to do everything we needed to on foot and by public transportation.
