I would have given 5 stars if the elevator had been working when we arrived. But the host was SO responsive. She requested and got emergency repair so the elevator worked by our second day there. She also offered alternate (first & third floor) apartments if we preferred that in the event that the elevator didn't get fixed quickly.
Plenty of good quality towels. Unusual to find a place at this price with both king-sized and queen-sized beds. We only used the king, and it was very comfortable.
I would definitely stay at this apartment again next time we're in Chicago, especially if it's for a Cubs game.
