Central and spacious but let down by a few basics
Pros:
- Highly professional, cheerful staff.
- Central location, close to Magnificent Mile, Lake Shore Drive, Navy Pier. 
- Rooms are large, including a living room.
- Bed is very comfortable.
- Breakfast includes delicious omelets, freshly made to order. 
- Complimentary snacks (pretty generous and tasty) every evening in the lobby.
- Impressive atrium, with super-fast glass elevators.
- Nice pool (although pretty small)
Cons (The basics):
- Bedroom walls could do with much better sound proofing. You may well get woken by people talking in a neighboring room. Confirmed in two different rooms.
- Bedroom windows could also do with better sound proofing. Lots of car horn sounds and even the growl of their engines. Confirmed in two different rooms.
- Black out curtains are difficult to close in such a way that no light comes in.
Cons (Additional observations):
- Tiny kitchen area is practical, but not even spoons are provided (e.g. for coffee/tea).
- Shampoo and conditioner provided, but difficult to open, especially with wet hands. Also no easy place to store them once opened around the bath tub.
- Towel rack is placed far away from the bath tub, so don’t forget to prepare your towel BEFORE you get in the shower/bath.
- Some general wear and tear is visible, and rooms could do with a good all round dusting.
- Pool area could do with a few deck chairs!
All in all, a good hotel, but I have stayed in much better hotels (for less money) in central Chicago).
