I didn't have the privilege of meeting Henning in person, but he was a pleasure to deal with. All his correspondence was prompt and detailed, from acknowledging my initial enquiry to arrangements for my departure.
Special mention for how my flight cancellation was handled. I notified the contact person Henning had arranged for my arrival/check-in that I would be delayed by an unknown amount of time, and the friendly response assured me that wouldn't be a problem. I finally arrived in Berlin 24 hours later and was met at Bayerischer Platz as previously arranged with no fuss at all.
Not only. that, Henning contacted me a few days later to check I wished to extend my stay. A lovely thought, and an offer I would have liked to accept if it wasn't for commitments back home.
His apartment is light and gets a lovely breeze when you open some windows. Nice, modern kitchen and bathroom.
In a quiet street with a supermarket and cafes across the road. A few minutes walk from Bayerischer Platz in one direction, and Schöneberg Rathaus (and weekend fleamarket) in the other. A few stations on the U4 to Nollendorfplatz or 15 minutes on the U7 to Kreuzberg.
A lovely apartment, in a great location, with an organised and considerate host.
