Amazing location!
We stayed at the Hilton Suites Chicago for 6 nights in July 2012 and would definitely stay there again. The location is AMAZING - a 5 minute way to the Water Tower mall, Bloomingdales, Cheesecake Factory, etc, etc. There is also a variety stores/mini grocery store right across the road which was so handy for picking up snacks, drinks, wine, etc to have in the room. Taxis were always readily available outside the hotel - thanks to the amazing lady at the front door! We ate in the hotel restaurant almost every morning and it was a great spot for a quick bite to eat before starting the day.
Our room was on the 15th floor overlooking the back of the building and it was very quiet. The suite worked well for us travelling with a 6 year old - and doors provided decent sound quieting between the spaces when our son went to bed. And after a few meals eating delish deep dish pizza at Uno and Giardarnos (yum to both!) was really handy to have the fridge and microwave (and pull out dining table) for a low key 'leftover' dinner!
We went swimming several times and the pool was small-ish but our son loved it - and the hot tub too. We went to Chicago to see a Cubs game and Wrigley Stadium too (definitely check out the tour) and took a train to Milwaukee to see a baseball game there too.
We would definitely stay at this hotel again with our son. It's a convenient spot for family travel for sure.
