We stayed at the Staybridge Suites on our way to the Badlands etc. We found the hotel to be clean, and the staff accommodating. Our room was a suite room with a king bed and sofa sleeper in the outer room. I have a bad back and I found the mattress to be comfortable and firm enough for me to sleep well. We needed to stay at this hotel again on our way back home a few days later, and asked for that room again. Much to our surprise, Bert ( Guest Service Manager) was able to assign that particular room again for us. My back thanks her! Good continental breakfast, good room, good staff.....we would highly recommend this hotel.
