Mike is a great and super friendly host. The caravan is cozy, even though it was quite small it was very nice. The train tracks literally next to the caravan were a bit disturbing, especially during the day, luckily enough I slept like a baby :)
Again, Mike is very hospitable and took the time to explain everything, there is a nice bath in the main building and with some restaurants and a bakery around the corner this is a perfect spot. A ten minute walk from Ostkreuz station and Friedrichshain, it's location is perfect.
