Alice was very welcoming and correct. She'd leave you alone if that's your preference, or invite you to play bridge with her friends... Location is excellent on 2 subway lines. I found myself touring mostly East Berlin, but still I found the subway rides very relaxing and a great opportunity for people watching. The place itself is great - lots of space, high ceilings, tons of electrical outlets, bright lights. Solid wifi with no issues. Ask Alice about local events. Grocery store very conveniently located at the entrance to the subway station, and very cheap too. Another great opportunity for people watching. All in all a very enjoyable experience.
