Nina's place was brilliant for our needs - very central, lots of space, and everything we needed to make ourselves at home. Her friend met us (and didn't complain when we were slightly late due to getting a little lost) at the apartment, and showed us where the supermarket (60 seconds down the road) was, and all over the flat. The road is quiet and secure and very easy to jump on a bus/Ubahn to get to the centre. Cannot fault anything - we would really really reccomend!
