I have seen other reviews mention the train - let me cover that first: it wasn't that bad. I brought ear plugs and we were prepared to need them, but the train wasn't the noticable unless we were just sitting around watching TV. Who comes to Chicago to watch TV?
The building is really cool - thick wooden support beams, the closet in the unit used to be an elevator shaft. Everything about the building was just neat.
The location is great - about two or three blocks from a train station, and one block from a full service grocery store, and a Dunkin Donuts. Can't get much better than that.
Nicole was super communicative and we were very satisfied with our stay.
