Two more ideas:
The first is from Otto Spaniol: "Personally, I made good experience with the Hotel Limmathof. It is *very* centrally located, just opposite to the Central tramway stop and next door to the Polybahn entrance and the walking district. 5 minutes from main station. The price was just 100 SFR a night."
The second is an offer from the Intercontinental for those of you who have attended IFIP or ACM conferences there. (The former Nova Park.) "Friday & Saturday: Business Room at CHF 173.- per room, per night Executive Room at CHF 243.- per room, per night
Sunday: Business Room at CHF 185.- per room, per night Executive Room at CHF 270.- per room per night
Breakfast: CHF 28.- per person, per day
These are IBM-Corporate Rates including service, tax and VAT."
Looking forward and with best regards, Harry
