I stayed at Claudius and Barbara’s apt for 3 months while working and exploring Berlin. The room was very spacious and cozy with high ceilings and great natural light. After long work days and traveling on the weekends it was a great space to come back to. It’s an excellent location in Neukölln with tons of bars, restaurants, and coffee shops in walking distance. Also very close to the U7 and U8 subway lines which was really helpful for exploring the city and commuting to downtown for work.
A cleaner came to clean the bathrooms once a week which was super appreciated, however the kitchen wasn’t always very clean.
The only other issue that arose was that the hot water went out three different times in the apartment, which was always met with a quick response from Barbara/Claudius. It was disruptive since I was commuting into work but they worked as quickly as they could to fix it.
