We recently stayed at the 3BR penthouse and had a great time. The space was very clean and stylish, yet simple. The three bedrooms were nice to have and the couch in the living area also is a pull out sleeper, so there is plenty of space. The location of this couldn't have been better, allowing us to walk a lot of places, including the Riverwalk, Millennium Park, Art Institute and plenty of walkable places to get food as well. Views were great from the place, and it is one floor below the rooftop deck with great views as well.
We found it best to use the parking garage directly across Lake Street (60 E Lake Street) and used the iParkit app for the best rates, which included in and out access (Spot Hero did not allow in and out access at this garage).
Overall, great space, very clean and wonderful location if you are looking for a place in the city to stay.
