Units in the Studio Gang-designed Aqua tower in the Lakeshore East community don't list everyday, which makes this 3,500 square foot duplex penthouse on the 80th and 81st floors particularly special. According to the listing, this three bedroom, three and a half bathroom unit boasts custom finishes and is a perfect place for entertaining due to its size. However, the most exciting thing about it is its awesome skyline views and its long rows of wrap-around balconies on each level. The cherry on top is the two included parking spaces. This one is seeking big spenders with its $6 million price tag.
