That being said, I am very sensitive to the odor of smoke and could smell it through the ventilation system in my non-smoking room. The even numbered floors are non-smoking. Soco Tower has smoking and non smoking rooms. However, this tower is closest to the hotel lobby/front desk and the hotel parking deck/valet. The only downside to this tower is if you like taking a nice relaxing bath, because all the rooms only have walk in showers.
