Loved this place! There were four of us (one couple and two singles) and the layout of the apartment gave us plenty of space to spread out and not feel like we were on top of each other...but space to hang out when we wanted to. Apartment was extremely well equipped with lots of little extra touches throughout -- coffee, creamer, and sweeteners for the Keurig, soda, water, and beer in the fridge, as well as an assortment of snacks. I'm pretty sure the Ego Waffles in the freezer saved one of our guys one morning after we closed the Dark Horse bar downstairs :-). Location couldn't be better...just a couple of blocks from Wrigley with bars and restaurants galore. Noise from the bars downstairs never bothered us (see note about about closing the Dark Horse ;-)), and we put our friend who lives near a commuter train in the back bedroom closet to the train - although both he and the guy in the middle bedroom said noise from the train never bothered them (and, if you're a light sleeper, Naomi and JJ provide ear plugs in all bedrooms).
Be advised that as advertised, it's a third floor walk-up. One long staircase followed by two shorter ones. You'll definitely get your exercise during your stay. But what awaits at the top of the stairs is worth it!
Great communication before, during, and after the trip, and super flexible hosts who were nice enough to work with us on arrival and departure time. All in all a stellar experience. We'll be back!
