We stayed at the downtown Hyatt Regency, near the convention center, while in Minneapolis in mid-August. The place was great. It was quiet and seemed to be well run. The room was wonderful (can't beat those Hyatt mattresses). The restaurant and bar were fun. And the location was on the edge of both the Nicolett Mall and a greenway that stretched to a nearby park. We didn't need a car -- instead we caught a free bus heading down the mall or walked the 8 blocks or so over to the light rail system. We'll stay here the next time we are in town if we can.
