First off all, the neighborhood this apartment is located in, is an absolute gem. Restaurants, night life, park, lake, bookshops. You name it, it has it. It is just the right distance from downtown that you can still go and see all the tourist spots but also get a local feel. It is also well connected, although if you prefer the train to the bus, you might have to walk for about 10 mins.
The apartment itself is cute and perfect for one or two visitors. It is very neat with all the basic needs present. I didn't realize this until later, but there is also a coin operated laundry in the 1st floor. The hosts were great at communicating and checking in on everything. Like others have mentioned, the building can be a little bit creaky and loud at times, but I was not personally bothered by it.
Overall, this is a good place to stay if you are visiting Chicago. I know where I will stay, if I visit again!
