We came to Chicago for a bachelor party and trying to find a place for 15 people was non-trivial. But once we saw the listing for Casey's place we knew we found the perfect spot. The location was great with lots of bars, restaurants and a grocery/liquor store nearby. The amenities were excellent: a huge living room to hangout in, ample sleeping space and having your own rooftop terrace really tops it off.
It is split into 2 units but all of us were able to comfortably hangout in one area which was the only thing we worried about. Casey was very helpful as we were planning our trip and extremely responsive. Would definitely stay there again with a large group.
