Jose was very helpful, and always quick to respond to any text messages or calls.
The location is in a family-friendly Hispanic community, but there are not a lot of options nearby for late night food fixes. There is a Walgreens within walking distance, but you have to cross a busy street, so be prepared to dart across quickly.
This is on the lower level of a 2-unit dwelling, and there is another apartment above, so if you plan to be up late or will be coming and going late at night, you may want to take that into consideration.
The roll-away bed was comfortable enough for a roll-away, but it didn't have bedding, so if you're planning on having a 5th person, you may want to bring some extra blankets or ask Jose in advance (I'm sure he would accommodate your needs).
If you are planning on using the trains while in Chicago, I suggest parking in China Town right at the train stop. This location isn't very close to the trains, though, so if you won't have your own car, you may want to keep that in mind. I do think it's within about 6 or 8 blocks of a bus stop.
