I just checked also. It seems that the cheapest rate now is pre-paid at 172 EUR. Corporate rates are around EUR 175. 31 K on points. For my tastes this is priced too highly for this location. Hopefully the prices will settle at a lower rate. 135 is about the rate at which I might bite.
Please note that this hotel charges a city tax of EUR 3 per person per night. It will be included if you have checked off the box "include all taxes and fees", but probably not if you are booking an award stay.
