The place was exactly what we needed. It was super clean and the bathroom were really nice. The size was plenty for the four of us. The bedrooms are spacious and the beds are very comfortable. The pots and pans in the kitchen could be slightly larger when cooking for 4 or more. Otherwise, the kitchen had everything we needed.
We had a perfect stay. I happened to meet Simon at check-in and he was extremely nice. At the end of your stay you even get a little ThankYou bag. Wedding itself isn't the nicest part of Berlin, but the apartment is close to public transportation and an easy 30 minute walk to the main train station. Overall a great place to stay!
