My family and I stayed here in June, 2014 for a week, and everything from the time we arrived until the time we left was perfect. The condo looked even better in real life than it did in the photos. It's HUGE, clean, modern, with every amenity we could possibly need.
The unit itself had two large bedrooms and two large bathrooms, a full kitchen, dining area, and living room, plus in suite laundry and lots of storage space for suitcases. The balcony was massive with a great view of the city, and you could even see the lake too! The building is in a great location just a few blocks away from Michigan ave, and right above a grocery store which came in handy for stocking up on snacks and beverages. It's also a couple blocks away from Eataly, which has a wide variety of food options.
Getting around the city was easy, we had a car and there was parking available which was fantastic. Even if you are not driving, you are in a central location so it's easy to walk to either end of Michigan ave, or take the train to get to other parts of the city.
I would absolutely stay at this property again, in fact I don't see any reason to ever stay at a hotel here in Chicago again and I would definitely recommend it to others.
