Stephan and Sofia are great hosts, they left a packet of sweets for the kids, which the kids loved, and they also provided a map with the local restaurants nearby. The apartment is well-equipped and is very well located, with easy access to public transport and the major sights.
For vintage bike enthusiasts we can highly recommend a cafe called Steel Vintage Bikes, where you can dine and shop for beautifully restored bikes and accessories, which is not far from the Brandenburg Gate.
