It was an amazing experience. The apartment is in a beautiful and lively area of Berlin, nice restaurants and bars, green areas. It was absolutely quiet at night, even though being in a busy area. The house is very cool, you feel like a local, loved the vibes. The kitchen is well equipped, the rooms are big and comfortable, the whole apartment is clean and neat.
Location is perfect, U bahn is very close, and Alexanderplatz is also 20 minutes walk away.
Björn is very welcoming, nice and helpful. Can't wait to return again. :)
