We brought two kids and ended up on the 16th floor ...wish it was higher up but we had a great view and small balcony. Kasa service desk was super helpful with everything, as was their electronic messaging (very quick & concise). The building was located in a great spot for various parts of the city (not just the Magnificent Mile) and we really enjoyed our stay. There was one issue with check-in being delayed a bit due to housekeeping being behind schedule, but a clean room was preferred over checking-in on time. The elevators (including access to) were a bit confusing and took a while sometimes, but probably only because they were limited to 4 occupants (per COVID provision). We also had trouble with the keycode (unlocking) our door but eventually figured it out. These last few things might be why this review didn't get a perfect review score, but would have otherwise been happy to give FIVE STARS!
