While I didn't get to meet Kezia in person, her friendly housemates welcomed me in, and helped me settle in. Kezia in general was also super quick to respond and very helpful, so it wasn't a problem at all. The place is a perfect spot to explore Mitte and beyond Berlin. And their shower head was probably the best showerhead I've experienced - steady and strong water pressure, which I always appreciate. Would recommend and stay again!
