I deeply enjoyed my post-renovation stay at the Park Hyatt Chicago and found the entire hotel to be a vast improvement than it was pre-renovation. I would easily return - Chicago has so many good choices it's hard to choose!

Pros:

• Breakfast at NoMI is so fantastic - my pancakes, eggs, bacon, and coffee were even more fantastic than the beautiful Lake Michigan view and was fully covered (came out to around $45)
• Upgraded to a Chicago Avenue Suite on the 18th (top) floor
• Service was much better and uniform than my last stay - bellhop rang in my name to the front desk before check-in, everyone saying Good Morning across the lobby as I walked off the elevator
• Suite was frankly beautiful, and furnishings were quite comfortable
• They have kept many of the great aspects - bathrooms open to windows, window benches
• No issue with 4 PM checkout
• Turndown service offered
• Handwritten note from the GM (though, no welcome gift - Marriott has spoiled me with the macarons they keep giving me)
• Shower was fantastic - turn on both heads for a light but full water flow that is peaceful and effective
• Bean-shaped tub was much more comfortable than it looks
• Automated Toto washlet toilets
• I've never seen automated windows shades so quiet

Neutral:

• The bed linens had a strong similarity to Hyatt Regency linens and were not as plush as other 5 star hotels in competing brands - regardless, I slept very well, and the bed was more comfortable than it looked

Cons:

• Room was quoted as being ready in 1 hour as no one was occupying it, but it was closer to 1 hour and 45 minutes
• Mirror lights in dressing room non-functional - was told these were disabled across the hotel for safety
• No real working desk - small table and chair - I chose to work on the window bench, which was kind of novel and not too uncomfortable
