My 2 friends and I decided to stay in Berlin for 3 days before we head back home to San Francisco and Carsten's apartment was just perfect for us. It was definitely lovely, clean and the location was pretty much accessible to everything.

We met Carsten upon our arrival and he was very nice, accommodating and helpful. He replied promptly to my inquiries and answered all my questions.

If ever you have plans to go visit Berlin in the future, consider staying at Carsten's apartment. We highly recommended it! :)
