Stefan was a great host, he made the effort and met me at his place when I arrived at noon on a Wednesday ( in true Slovak fashion we had a shot as a welcome to his home ). The apartment is exactly as it looks in the pictures, the room is large and comfortable ( I was by myself but two people would have plenty of room ).
If you've never been to Berlin this area is awesome, the side streets have lots of interesting bars and restaurants, being on the border of Neukolln and Kreuzberg is a perfect place to be; plenty to see and do within walking distance, very easy to subway or bike to Mitte or Prenzlauer Berg, also going a bit east to Friedrichshain where it's still a little rundown/sketch/cool as shit is easy on the subway and even walking is >30mins.

Stefan is easy going, he was generous, and even though we didn't hang out much ( busy and on different schedules ) we still talked in the house and found the time to hit a local bar one night.

Totally recommend this place, don't think twice just book it ( access to a bike is also a great bonus ).

Have fun in Berlin y'all, it's a great city!
