Firstly, Angélica really helped me when I was in desperate need of somewhere to stay. I was coming to Chicago to take part in the marathon, yet two weeks before the run my original host cancelled with no prior warning.
A big benefit to staying here was that it was close to the Blue Line train so whether making the journey to/from O'Hare or going downtown, it was made easier by having that public transport nearby.
A good place to explore the city of Chicago.
