I really enjoyed staying at Anton's apartment. The place it's really clean and cozy and it has everything you need for a pleasant stay. It's in a very quiet and calm neighborhood and it is just across the street from the public transportation (which is all we needed to travel across Berlin, it's 25 minutes from city center) .
Anton gave me all the information needed to get to the apartment and although I never met him in person, judging by the way he communicates I can say he's a nice person. Also he has very good taste in music!
His maid is a really nice lady to which we easily communicated and even helped us with a lost jacket.
I really recommend Anton's apartment to anyone wishing for a nice stay in Belin!
