Frederik is an easy going and nice person, he was waiting for me at arrival and explain me all about his flat. He was a great host.
The appartment is cosy, clean, located in a calm area but close to metro station and a lot of supermarket, shops, restaurants. The appartment has everything you need to rest, cook, and enjoy your time in Berlin.
I recomend his appartment strongly and I would book it again if it is free in my next visit to Berlin.
Thanks for everything Frederik!
