Calvin's place was great value for money! I had a business conference at the McCormick center which was a 15 minute walk from the house (the bus is supposed to be even quicker). I could catch the subway to-and-from the airport. And I could even take a walk to the lake and downtown Chicago (it takes an hour-and-a-half but is fun as a tourist).
Living in Chinatown was lots of fun. There are lots of great little restaurants serving every type of Chinese food. There are also a couple of gift and clothing shops.
The room I got was very clean. I got a real bed that was nice and firm (firmer than a hotel bed). There were two shared bathrooms which meant I never had to wait. The kitchen was serviceable with a large refrigerator.
I took off a star for the noisy fan that occasionally woke me at night. But I put a star back on for having the convenience of Calvin's mother living downstairs. She was a super nice lady who rescued me when I locked myself out of my room after taking an early morning shower.
