Fantastic place! Perched at the top of a 5 storey building, Arne's place offers great views and a very comfortable stay.
The penthouse aspect is not overstated. You get your own spacious terrace spanning three sides of the building, overlooking the park and the Berlin skyline.
The room is very bright and spacious with a large comfortable bed, a large desk/table, coffee machine, mini fridge and access to a private bathroom down the hallway. Everything is very clean and well maintained. The WiFi is good if you need to get some work done or stream video.
The neighbourhood is quiet and residential. There is free parking on the road in front of the building. A metro station is located nearby and that makes traveling to inner Berlin quick and practical.
We enjoyed our conversations with Arne, his recommendations of places to visit (go see Potsdam!), his attention to detail in arranging the space (we even had some water bottles in the fridge), and the fact that we were given a lot of privacy to relax and enjoy the space.
You're getting a rare opportunity to stay in a memorable place. Book it quickly.
