Wonderful flat at the heart of Prenzlauer Berg. We stayed at Louis' flat for a few weeks and it's very suitable for long-term stays as it's spacious and feels very homely. It's also well suited for young kids (we had a 1-year old with us) as the bedrooms are really quiet, it doesn't get too hot in the summer and there are lots of playgrounds close by. Louis was a great host, super quick to respond and very helpful.
Would definitely stay again.
