Never thought I would stay overnight in the red-light district of Frankfurt. Hotel Nizza is absolutely charming. Beautiful ceiling and bathroom fixtures, excellent bed, rugs, wooden floors, antiques, wireles LAN. A little roof terrace looks up onto the majestic skyscrapers. I checked in just before midnight in front of, what, an actress, probably, with a big bouquet of red roses. People at breakfast, at ease, reading. Just outside yesterday morning a black hooker in yellow platform shoes. That will do fine for a sunrise. Then two days of teaching inside Norman Foster’s beautiful Commerzbank HQ. A good gig.
