Matthew's apartment is amazing. There is a ton of space, the beds are incredibly comfortable, and the location cannot be beat. Matthew and his girlfriend Cristina were more than accommodating and their communication was great! There is a poker table and a TON of records, which my pals and I just loved. The bar/wine wall is off limits though ;) The pink line is right down the road and you can walk to a lot of restaurants/bars. Check in/out was a breeze as well.
A couple items of note: this is located on the fourth floor with no elevators. It wasn't a problem for us, but could be for others. The water heater is small, and again, it wasn't a problem for us, but if you like to take long showers be prepared for cold water!
Seriously, my friends and I were so impressed with this apartment and will 100% stay again for future Chicago trips.
