Stefan's place is fantastic. It was perfect for my stay in Berlin. I love how it is right in-between tourist Berlin (if you want to see all the sights) and more of a local Berlin (if cafe and bar hoping is more your thing). The street is quiet and as a solo traveller I felt safe at all hours of the day & night, there's even a great coffee shop right across the road - what more could you ask for?! Would highly recommend, Francesca.
