If it were actually possible I would give Hannes 6 stars out of 5 for being such a great host. Throughout my stay Hannes made sure that I was comfortable and very friendly. Hannes offered me food during my stay and even offered to help me register a prepaid SIM card.
Hannes' house is cozy and beautiful. I had no issues with my room and there are plenty of power outlets to charge your things. The living room and bathroom are very nice, and the garden space is the perfect space to sit down and enjoy a cold beer.
The location of Hannes' home itself is fantastic as well. His home is close to Schonefeld airport via transportation but not too close so you aren't disturbed by airplanes taking off. The neighborhood is quiet and safe, and there are various public transport stops/stations nearby so getting around Berlin is quite easy.
If you have the chance to book a stay here, don't miss out!
