We took the train for a getaway to Chicago, so we wanted to stay somewhere downtown that was close to the L and bus lines. The Blackstone was excellent. The building itself is gorgeous and is within walking distance to Grant park, many restaurants and mass transit. The amenities are first class and the staff was very helpful. We arrived early, and they stored our luggage (free of charge) so we could go sightseeing unencumbered. One minor thing - the bathroom had a sliding frosted door, with a small gap between the door and the wall, so privacy was limited. Not a big deal because I was traveling with my partner of 12 years, but it could be uncomfortable in some circumstances. Overall, we had an excellent time and could not have asked for a better hotel!
