This flat is great, a good size for the 3 of us. Its nice to have a small balcony out the back, the weather was fantastic the week we were there so it was nice to be able to sit out and enjoy breakfast in the sun.
I guess the only downside is the it is on the top floor so there are a lot of steps to get to the flat!
Jon's flat was a great location for exploring the Prenzlauer Berg area.
