5th floor (the only floor with sea view) is below the level of the pool, chlorine vapors (gas) is heavier than air which means that the excessive chemicals in the pool flooded the 5th floor making the air very uncomfortably chlorinated/bromide strong. Despite opening the exterior doors, placing a wet towel under the hotel door, the caustic odor from the pool totally permeated our room. Front desk staff acknowledged that this was a problem and apologized, but were unable to give us another room due to booking. Other than that the hotel was nice, but management really needs to consider adding external ventilation to the elevated 5th floor pool to remove these caustic vapors. We barely slept that evening and that was too bad for an otherwise nice hotel
