Mark's place was perfect. For someone who had never been to Chicago before...completely unaware of the area...I was relieved to have stayed at such a convenient location. Logan Square is a good mix of nice quiet residential with trendy highly rated restaurants and bars within walking distance. The blue line is less than a 10 min walk which can get you to O'Hare, other neighborhoods like Wicker Park, and downtown Chicago, easy. The space itself was a generous size. The bed was super comfy. Being able to let ourselves in without disturbing anyone was a huge plus as well. All around great vacation. I'd recommend to anyone wanting to visit Chicago.
