We didn't get the opportunity to meet Stephan, but he gave us instructions on how to obtain keys and enter the property. We had a little confusion but this was easily rectified when we called and got the correct info from Stephan. He was very quick at responding and very helpful with suggestions of local places to go and eat and relax. The apartment was very simple and clean with everything we needed for our stay. A nice size for our group of 3 people and the location was perfect for where we needed to be. The price was also very reasonable for us also. We hope we can stay here again when we visit Berlin!!
