We're sorry to hear that the heat was so oppressive. Unfortunately you were in New York during a heat wave and the one window in our apartment that can accommodate an air conditioner is also attached to the fire escape, meaning that installing an air conditioner would create a fire hazard.
We thought the fan in the bedroom would be sufficient as it is pretty powerful, and we had purchased an extra fan for the kitchen to better circulate air throughout the apartment, but unfortunately we cannot install air vents because we are only renters (as opposed to the owners of the building). Nevertheless, we will consider purchasing another, more powerful fan.
Hope your trip to New York was nevertheless enjoyable.
