Me and my friend had a very enjoyable stay at the apartment. The instructions were very clear for the house and also directions from the airport were provided which was really helpful, just make sure you leave the u-bahn by the right entrance! It was very cold but the apartment was warm. We didn't cook anything but did use the coffee machine which was a welcome touch. There is a Lidl just up the road which is useful.
The road the apartment is on is quiet and mostly residential, at first we were a little nervous of wandering late at night in the area but it is just like any big city and no problem.
I would definitely recommend the apartment, lots of transport links, cosy and everything you need for a short break. Thanks very much.
