1. We emailed F1-Kassel for directions using public transportation to the hotel and received a prompt reply in English. From the old Hauptbahnhof or Konigs Platz take bus 19 to the Gobeitzstrasse Stop. For two people, buy a "MultiTicket" which is good for 24-hours. F1-Kassel is located in an Industrial Park.

3. Be prepared for a small room with shower and toilet down the hall. Yes, German clean is standard and welcome.
4. Good electrical for charging camera/cellphone batteries.
5. Restaurant is next door at Ibis Hotel.
