Nowhere I know well appears on a search, although the QBic at Zuid can be OK, if you get a room with windows.
I'd be minded to try Daily Rooms apartments (on booking.com for €75/night), but I've never stayed there before. Location is great.
You could also look for the Carlson hotels deal (see the hotel deals forum) on the parkplaza.com website, expanding your search to all Carlson hotels.
