Marion's place is full of light and I used the balcony as often as work permitted. It's clean and cozy, refurbished but located in an old house with lots of charm. The location is better than anticipated - it's close to Schönhauser Allee station which gets you anywhere in Berlin fast. Which wasn't all that necessary, because I spent a lot of time relaxing in one of the countless little cafes and restaurants in the neighbourhood. The markets on Kollwitzplatz and Mauerpark are within easy walking distance. It's hard to imagine a better location for a visit to Berlin.
