Alan & Kasia were great hosts. Alan met us at the apartment to exchange keys. Our flight got in before official check-in, and without even having to ask he offered for us to drop our bags off while they finished up cleaning. Alan also gave us a quick overview of Berlin, neighborhoods to visit, etc. The apartment itself was great - pots and pans, a washing machine, strong shower pressure. It was also super conveniently close to public transportation to see the sights, and the neighborhood was also scenic to walk around. Can't say enough good things!
