Marty & Rob's place gives you a peaceful environment. If you're looking for a calm and safe AirBnB to stay, I totally recommend it. Also, the house has been 100% remodeled. We loved its zen decoration style withindoor plants and a beautiful garden outside.
Our 6 days in Chicago were amazing thanks to its location because you can move around without a rental car. This house is just one block away from CTA Bus (22 Route) that takes you directly to downtown in approximately 50 min.
The neighborhood gives you a sense of safety during day and night, so we walked around without any worries.
CONS: You might ask Marty for other bedroom (they also have one in first floor), if you have problems with walking up/down stairs since its located in third floor.
