Ion's space is clean, private, and affords an opportunity to meet a really wonderful family (if/when they are home).
Administratively, directions on what to expect and how to gain access to the home were very clear and the place was easy to find. Street parking, while typically a nightmare in larger cities, was available (multiple spots directly in front of the hosts' home) and free!
The host and I had lovely conversation (about kids, education, international travel, wine, coffee and more!) and he went above and beyond to make my stay in Chicago a great one! I would stay again!
