Ralph's apartment was absolutely perfect for our stay. We were a group of five people looking to explore Berlin for a long weekend and needed an apartment that was spacious and comfortable. This place is enormous - a ground floor apartment in a quiet residential block that easily accommodated all of us. We got in late due to airport issues and Ralph was happy to be there when we arrived to check us in. The apartment was very clean and well set out and perfectly placed near the u-bahn as well as only being 15 minutes walk to places like Potsdamer Platz. This is an ideal place for a group of friends and I highly reccommend staying here. Cheers Ralph!
