Overall, we enjoyed our stay at the Biddle House. The unit is older and could use with some updates, but was comfortable enough for the pair of us. Our main complaint was the slow Internet - we were trying to work from the unit and could barely manage video calls.
The location was phenomenal - close to the lake, the park, the train, and lots of restaurants in the Old Town area. Having free parking in a such a popular area was a great benefit as well! Thanks for your quick responses and for hosting us while we were in Chicago!
