We arrived early and Aidor, the security guard in the lobby locked up our bags for us so we could start our trip. Check in is at 4:30 pm on the 19th floor. Millennium Park, Chicago River walk and subway within walking distance. We had a tiny studio that was very comfortable. This is more like an apartment with full kitchen - fridge, stove, microwave, toaster & coffee maker. The AC is loud but powerful. The mattress is very old and soft - should be replaced. The room was clean, lots of towels plus shampoo and bar soap. There is no maid service during your stay but you will be charged for a cleaning service that comes in after you check out. Everyone was pleasant and helpful. Maybe we just got lucky with a newer room but we would definitely stay here again.
