The Sovereign was designed by architecht Walter W. Ahlschlager. At the time, its appointments and furnishings were, according to American Builder Magazine, the richest and most pleasing of the year among Chicago apartment hotels.
The rooms featured disappearing beds and mechanical refrigeration, while the “furnishings throughout breathe refinement and quiet elegance in accordance with the demands of the exclusive patronage which this apartment hotel enjoys.” Rentals ranged from $100 a month for a one-room apartment with dressing room and bath; $150 for a living room, dining room, kitchenette, entrance hall, dressing room, and bathroom; $260 for a three-room apartment; to $325 per month for the most desirable corner apartments.
Today the hotel is known as The Sovereign Apartments.
