We had a great time in Berlin - Fritz’ apartment is very conveniently located and totally fantastic! All communications were swift and friendly. We didn’t meet Fritz in person - his mother let us in and gave us some local tips including a street food market which we loved! The apartment was quiet and cosy despite its central location, it had everything we needed including many great bars and restaurants in the area. We accidentally left without our key one evening and Fritz’ dad kindly let us back in without a fuss - for which we were most grateful. Highly recommended.
