Lesley was a great host and super communicative to my messages. The apartment is exactly as described and the windows and high ceilings help make the place comfortable.
We walked a ton to wicker park / bucktown and Logan Square and took the bus to the downtown area so you should be okay with walking and taking public transit. The 3 day CTA pass was super handy! The blue line subway is also nearby to go to Ohare. I also highly recommend making reservations for Kai Zan. We love sushi and it was a highlight!
