The two bedroom two bathroom unit was exactly what we were looking for. The 5 of us were perfectly comfortable with two in each bedroom and one on the couch sofa. The location was perfect with easy access to tons of great restaurants, bars, the Michigan Ave. shops and there's a Whole Foods right across the street. The AC kept us cool during the day. It was great to have a balcony to enjoy the city sights and sounds. But you are right in the middle of the city, so be prepared to hear loud cars/motorcycles and fire engines every once in a while. The unit had plenty of clean towels, sheets and blankets for us. They also had a ton of K-Cup pods to make individual coffee. That was a very nice touch. Plenty of pots, pans, plates, and silverware to use if you want to cook and eat in. Another thing to be aware of is that these units are shared with people that live there, so you will be sharing the lobby and elevators with them. There were no issues with anyone, but it's not a hotel, so we felt like their guests and wanted to be respectful of the people that live in the building.
As for Kasa, the communication was excellent. I chose to just text back and forth with them. They always responded to my text within seconds. I did call them once to ask a question, and they answered right away to help me. They have great customer service! If you know you are arriving earlier than your check-in time, make sure you request an early check-in ahead of time. If they can grant you access early, then great, if they can't, then you'll need to figure out a place to go (with your luggage) to wait for the check-in time. Since this is not a hotel, the building could not hold our luggage for us. We ended up 30 minutes early and had to go to Joe and the Juice across the street. They had plenty of room for us and our bags to sit and grab some food/smoothies while we waited.
