7. -very good sound proofing, never heard any airport noiseWhat I didn't like:-no Safe, how does a business hotel not have a safe in this day an age?-we did not get our room cleaned one of the days there despite leaving the room early and returning late after our day trip to Santa Fe-A/C vent, directly over bed, when on super cold, when off hotWhat I hated:-pool, very disappointed it was unusable.
