Ashraf was EXTREMELY helpful and informative with all my questions and concerns. The place is clean, spacious and has a hipster vibe to it. It's literally right above the closest train station and behind a nice restaurant and a block from a grocery store and down the street from outlet malls and consumer strips. He even helped me translate my ticket which was in all German when I asked. Definitely would contact him again when I visit Berlin. Wifi is incredibly strong. Just an all around class act of a setup and host.
