Our stay in Berlin at Paul's place was great! Exactly what we needed. We didn't meet Paul, but he was super easy to communicate with and really flexible about check in and check out times. The key pick up and drop off was smooth and problem free. Paul's apartment is beautiful, well located close to grocery stores, cafes (a fantastic one just downstairs), and our favourite, the canal. We stayed at Paul's with two babies (4 and 6 months) and 3 adults and it couldn't be more comfortable (the only drawback, I suppose, was if you have small children, no elevator in the building, but we managed, and appreciated the distance of the apartment from the street). Paul was super hospitable and even left us some German beer. I highly recommend his place for a nice, relaxing stay in Berlin. Hope to stay there again!
