This is a list of hotels that one can stay in and still get fresh (relative to the air quality of the city or location) air when one sleeps. I am encouraging people to develop this resource via comments which I will then add to a list once I have confirmed that the venue meets the criteria:
Chicago:
Hotel Sax – fragrance in the lobby, however low/ no scent rooms and two windows that open. Can smell laundry detergent on linen/ towels. Friendly & helpful staff.
Embassy Suites, Schaumburg – scent free lobby, scent free rooms although one can smell laundry detergent on linen/ towels. Friendly & helpful staff.
