This Abnb description was perfect. It is a comfortable private room, well set up and appointed for a solo traveler or couple, with a comfortable bed and nice, shared bathroom and in very close walking distance to Berlin's efficient public transit system. The Schoenberg neighborhood is a nice combination of residential with local neighborhood restaurants / pubs / shops interspersed, but also with a commercial corridor and some unique points of interest (where JFK said "Ich bin ein Berliner"). Schonenberg also abuts the more active, hip Kreuzberg neighborhood.
Audrey is a warm, accommodating, organized and knowledgeable host - willing to share her knowledge if asked. In my case, she was also extremely flexible - as I requested to stay very last-minute - and even though she couldn't greet me personally, she quickly found a way to have a good friend / neighbor greet me and get me oriented. She also made sure I found my way utilizing public transit as I traveled in from Hamburg - with very clear and precise directions. Her "book" of recommendations is a great feature and quite self explanatory. And once we caught up in the late morning, she offered even more advice and it was even more fun clear how warm and inviting Audrey is. It made wish I could stay longer.
