Alexandra was a very nice and accommodating host. Her apartment is situated in a nice part of town not too far from a train stop that is only 2 stops from Alexanderplaz, where you can pretty much get to anywhere from. There is also a grocery store right across the street which makes it very convenient to buy food to make in the kitchen. The apartment itself is awesome! Its huge with a very nice updated kitchen and bathroom, which are probably the nicest of both we saw on our whole 3 week trip. The room is very big with plenty of space for you to keep your things, and the bed is pretty comfortable. I would highly recommend staying with Alexandra when coming to Berlin!
