We've stayed in Airbnb's all over the US and Canada & this is by far the best place we've ever stayed. Ken has so many details that really take this place to the next level. Everything is clearly labeled so you're not searching for anything, the apt is very nice & very clean, the kitchen is well equipped and there is even a coffee maker with coffee!
If you have more than 2 people I would definitely recommend staying here. We had 4 adults and the space worked perfectly for us, there is plenty of room to spread out & not feel like you're all over each other.
There were clear instructions on how to park (for free! - hard to find in Chicago). Ken was always very quick to respond to any questions & very helpful with any questions we had.
We mainly used the train to get around which is a very short walk from the apt. We went to two Pearl Jam shows at Wrigley while we were visiting & got home very late after each of them and always felt safe in the area. When we left to go home it was an easy walk to the blue line train that took us all the way to O'Hare. The only thing that I'd wish we'd looked into before was how the pink line works (which is what we mostly used for getting downtown & back to the apt), the pink line runs on a loop so on the way to downtown it's only ~ 5 stops but on the way back it's ~ 10 stops because you have to do the whole loop. We weren't expecting this extra time on the way back. It wasn't a big deal but would have been nice to know too.
Again, this a great place and we'd recommend it 1000 times over! Enjoy Chicago it's wonderful!
