Lena's flat is well located in West Kreuzberg, near the metro and some nice places to eat as well as secondhand shops if you fancy it !
You can easily access the center of the city by bus, metro or bike as well as other trendy areas of Berlin such as Neukolln and East Kreuzberg.
The flat is well equipped and spacious for two but it is to be noted that it is a basement flat (so dark) and we found it quite damp.
The rent a bike shop advised by Lena doesn't speak a word of English...
Google translate could be your friend friend or you can easily find another bike rental in the area.
We recommend.
