PROS: Dino is very responsive and check-in/check-out was a breeze. The studio is in an excellent location with tons of restaurants nearby, a bus stop right outside, train station two blocks away, and a grocery store two blocks away as well. You can easily walk to the best parts of Chicago and take the train/bus everywhere else. Studio was well cleaned and had utensils, extra towels, toilet paper, etc... Window unit A/C and heater worked very well.
CONS: studio is tiny, my guess is around 250 sq ft. You can sit on the toilet, wash your hands in the sink, and put your feet in the bath tub all at the same time. Building was built in the 1920's and probably hasnt been updated since the 70's. Everything creaks, moans, and smells. Tons of street noise with honking and sirens, bring earplugs if you aren't used to it. Hot water pressure was very low.
If you're a single person and you're just looking for a cheap place to stay in one of the best areas of Chicago, then this is a good place.
