Actually stayed with Beatrix for a few weeks. Beautiful apartment in historic art nouveau building and area with numerous and varied retailers, restaurants, coffee shops, and local public transport options within a few short blocks walk. Beatrix was a lovely hostess and the room was spacious and nicely appointed with a beautiful picture window onto a courtyard. Exclusive bathroom for guest was brand new. I would definitely attempt to stay with Beatrix again on a return trip to Berlin and wholeheartedly recommend her accommodation to others.
