Not the cleanest higher end hotel . Just fair. Very drab atmosphere. Pool out of order still. Somebody had a sunflower seed fest n they were left all over the floor for the days i was there, front desk at check in i dont think she wanted to be there that day. And in this climate an ev charger would have been nice for the price i paod to stay there. But the bed was comfortable #lasttime

Although our stay here actually didn't occur I'll comment because of how well things were handled. There was a last minute change that had us without a room there for the first of two nights. The manager called me the morning of our scheduled check in telling me that the hotel did not have a room for the first night. I didn't know that could happen. The manager had already found another hotel that was only 2 blocks away and set that up for us. He also comp'ed the first day. We decided to stay at the new hotel for both nights for convience. We stopped by the Kellogg to meet the manager and say thank you for handling the situation so well.
