I didn't get to meet Mark in person during my stay, but he was such a great host regardless! He was very easy to communicate with and very welcoming. He even provided some great food/drink/etc recommendations for the area! Check-in was a breeze and the place was very clean and tidy, just as photographed. Mark made sure prior to booking that we were aware the tenants upstairs are early risers and could sometimes be heard through the floorboard/ceiling. I didn't find it problematic, but if you're a very light sleeper it might be a concern. Also, as others have mentioned, it's a basement apartment with lower ceilings -- taller folks (6ft+) will want to be careful.

Overall, it's a great studio (super comfy bed, clean bathroom, full kitchen) and I would definitely recommend it and stay again the next time I'm in Chicago!
