Considering the Hotel Hasselkuss in Essen?

See the city district Kettwig... by Bagillbaer
See the city district Kettwig (in the South, quite a way from the city centre). It's very picturesque - at least mostly... some ugly spots still need to be jazzed up, but the rest is definitely worth a look. Kettwig lies around the banks of the river Ruhr, it makes a very nice bike tour if you start at the Baldeney lake in Kupferdreh (or even a bit further up the river in Steele) and then go on to Kettwig.
Loads of Fachwerkhäuser, narrow lanes, lovely Biergärten... a little outside the town lies Schloss Hugenpoet, a top class hotel and pretty castle. See a mass of pictures in my Kettwig-travelogue.
