Wow. This is a great hotel. It is so artistic and beautiful. We had an 11th floor King room for two nights, using Hyatt points.
Pros (well, some of them -- there are so many!): The room was gorgeous. There was no lake view, but our city view was lovely. The window seat was a nice touch. There were electric blinds and also black out blinds. The bathroom was amazing, with so many amenities and a two person jacuzzi tub for two, complete with bath salts and candles. It was a getaway without kids, so the romantic room was appreciated by my husband and me. The bath amenities were so nice. The staff were warm, friendly and helpful. The restaurant, NoMi (named for North Michigan) was beautiful with huge windows looking over the city and lake. We had a wonderful lunch (salmon for me and sushi for my husband) that was to die for. We later had an equally impressive breakfast, and even got to shake the hand of a serious, big time celebrity two tables down from us. The afternoon lemonade and iced tea was greatly appreciated as the temperatures soared to 100 degrees. The hotel is wonderfully located on the Magnificent Mile, walking distance to the river, the lake, the beach, Navy Pier, House of Blues, the Hancock Center, and scores of restaurants and retail shops. We took an architectural cruise and a bike tour and walked to both. We saw a show at Second City - we walked there (about 1.4 miles) and took a cab back.
Cons: Almost none! There was no coffee machine. Though coffee was available in the lobby it would have been nice not to have to shower and dress before getting that first cup. Street noise was a minor annoyance. A higher floor would have been nice, but it would certainly not stop me from coming to this hotel.
Heck, I'd like to move in!!
