The Gxxxx bonus is usually with regular stays, not pricelines stays.
The Cleveland Arcade is a fairly decent property with wireless internet access in the lobby (free when I was last there in April). It is a renovated historical building and is on historical registar. The rooms vary a lot since many rooms are different sizes.. Parking can be gotten for free on the weekends on 6th street or across in front of the library.
Have not stayed in the Penthouse suite but got upgraded to the Presidential Suite a couple of years ago and it had a lobby with powder room, very very long living room / lounge, dining room, kitchen, king bedroom and bathroom with both a jacuzzi bath and shower with the spa type shower head ^ Nice to be drinking cava while taking a whirlpool bath
