Natasha's apartment was exactly what my family was looking for. Four adults and two young children easily shared the two bedroom/two bathroom space; our bedroom was roomy enough for a pack 'n' play and quiet enough for the kids to sleep in the other room while adults hung out in the living room area. While we could hear the El below every once in a while, it did not keep us awake and was very typical of being in a city.
The location was unbeatable - we were able to walk to Milennium Park, restaurants, and the train easily. Were my kids a bit older, we would have been able to make it even farther afield to Michigan Ave and the Museum Campus too. Natasha was very responsive to inquiries and provided a lot of information up front, including how to find parking and luggage storage. I would recommend Natasha's apartment wholeheartedly for anyone looking for the Chicago Loop experience.
