Breakfast was good. Bed were comfortable. Sink drained slow. Ants in bathroom which is odd since we’re on the 3rd floor. Only gave us 1 roll of thin TP. Website had an outdoor pool turned out to be a nearby attraction and was misleading. Would have book elsewhere. Fitness center was smaller than the hotel room and a joke but there’s a planet fitness 30 min away. Definitely wouldn’t stay at a comfort inn again.

Property needs updating. Gym has most of the equipment not working. Room doors don’t seal light from hallway which means noise comes through as well. No bathroom in pool area. Overall price is in line with property. Breakfast was very good. Staff was attentive.
