Can't go wrong
I'll keep this short -- if you're looking for a fantastic place to stay in Chicago, the Waldorf is an excellent choice. Beautiful property with gorgeous rooms and excellent service. We loved the Gold Coast location, but just be aware that it's a 15-20 min walk from the river if your activities will be focused more in that area.
This is my new fave hotel in Chicago. It used to be the Conrad, which is also awesome, but the Waldorf just surpassed it. Looking forward to coming back.
