We had a wonderful stay at Biddle House #2. The location was excellent and we felt safe traversing the neighborhood. The proximity to the Brown line made it very easy to get to wherever we wanted to go. Only mistake was adding four 7-day CTA passes to one Ventra card after reading that you could use the card for up to 7 people. I ended up wasting $60 because I had to buy 3 more cards after I was told that you can only have one 7-day pass per card. We rode the bus once, but mainly used the L. There is a grocery store about a 15 minute walk east down Sedgwick. We emptied our suitcase and used it to transport food, water, and beer for the week. It would probably be a better idea to order groceries from a delivery service.
House fit our family of four nicely. Minor gripe that would not prevent us from staying again: 2 AC units were very loud, but you probably don't need them most of the time
We enjoyed the following during our week in Chicago:
Chicago Fire Soccer Game (fun)
Rage Against the Machine concerts Mon & Tues (amazing)
Art Institute (excellent)
Field Museum (very good)
Aquarium (average)
Chicago Cultural Center (free and definitely worth the trip)
Millennium Park (nice free orchestra concert)
Bean and Buckingham Fountain (checked off the list)
Second City (great night of laughs)
Lincoln Park Zoo (free, I've never been so close to Silverback gorillas before, make sure to go clockwise to avoid retracing your steps)
Link Park Conservatory ("free" w suggested donation - quick walk through)
Lincoln Park Lily Pond (decent)
Willis Tower (about what you would expect)
360 Observation Deck (should have been called 240 bc the West side was blocked for renovations)
Richard H Driehaus Museum (very cool, the tour was nice too)
Chicago Cubs game in Wrigley (bucket list, although the Cubs got blown out)
Walked along the lake ( put in 8.7 miles that day)
Architecture River Cruise (our docent was great)
Overall it was an excellent place to stay and a reprieve from the heat and humidity of a New Orleans summer. 2nd trip to Chicago and would like to go back some day.
