My friends and I (all grad students) were in town for a conference downtown. Pete's place was just what we needed. It was so close to the train, and getting downtown only took about 20-25 minutes. There are a lot of neat bars and restaurants in the area, and some SUPER panaderías. I would certainly look to stay at Pete's again if in the Chicago area.
The train is a little loud when it passes, but it doesn't run all night and honestly it's pretty soothing if you let. it be. The two beds were comfy, and the couch isn't bad at all! Plenty of space for our group of five adults. We didn't get to use the kitchen much, but it was well equipped. And the coffee maker was so great.
Pete himself was easy to get in contact with, and even though we didn't meet - check in was a piece of cake. Highly recommend!
