Leon's apartment is in great location. An underground station literally 50 metres away. It is also only a 10 minute work to a main station (Zoo) where there are lots of lines you can catch to just about anywhere in Berlin
The apartment is very light and spacious and is very well equipped.
It is on 5th floor so need to be able to carry your bags. But the steps are not steep and there are lots of landings so can have a break!

Apartment is in a great location if you like shopping, and lots of restaurants, Supermarket also very close
Would definately recommend

Only problem was there was only 1 set of keys, which we were able to work around, but a slight inconvenience at times
