We had a very good time in Christian's apartment. It's located close to Alexander Platz by tram, so it was always easy to plan our days and to get anywhere in the city. The room is very clean and roomy for two person. We had a shelf to put out our clothes and other stuff, and it's possible to make the room completely dark with the curtains or to enjoy the morning sunshine in the very comfortable bed. Christian is a very helpful and kind person. We had a perfect shelter for our 7 day long Berlin Trip, so I would like to recommend this great place and host! :)
