We were a group of friends travelling to Berlin for the first time and were fortunate to have Luke as out host. Since confirming our reservation Luke began helping us out all through to our departure by providing information on public transportation, places to notice around the apartment and even some help with translation.
He did all this during a period of being out of town!!
He was also very flexible with our check out time as well which was very helpful for us to spend our last day in Berlin hassle free with an evening flight.
The apartment itself was as advertised and on a very quiet street.
To summarize: GREAT STAY.
