The coffee makers are Mr. Coffee, so you'll need basket type filters. Full sized ones in the one bedroom. The studio we had (BWVs, but I think the coffee makers are the same) had a little four cup maker, but the filters still worked - it wasn't pretty, but it made good coffee. I understand they will also bring up a full sized maker for your studio it you ask.
The store will sell coffee filters as well, but only the bigger ones.
