Did not get to meet Julia und Lisa, but met their mother instead. She was really friendly and introduced us to the apartment. Moreover, she gave us suggestions on where to go. It was really heartwarming. The apartment is well located near to the U-Bahn, which made it really easy to travel around. The apartment looks small in the photos, but trust me it actually is pretty huge. My family of 5 stayed in there for 3 days with no issues. Would recommend it to others! :)
