I had the best time at Marko's apartment,
the apartment was really clean and the communication was quick as well.
Additionally the person who welcomed me at the apartment was really friendly and waited for me to hand over the keys and gave me some helpful tips regarding some good restaurants and cafes in the neighborhood.
There is also a train station near the apartment which made it easy to get to the city center.
I would definitely recommend this apartment to anybody who is visiting Berlin, I know for sure that I am staying here again the next time I'm in town.
Overall I can just say that it was one of my best Airbnb experiences I've ever had.
