We had a wonderful time in Mark's home for our girls reunion weekend. Plenty of space to spread out, with a big living room downstairs, a sitting area upstairs, and the roof top patio was *phenomenal* with fantastic views of the downtown Chicago skyline. I would say the place's aesthetic was "Your cool, child-free aunt who has traveled the world". Everything was clean, the beds were comfortable, and the location was fantastic. For coffee on the first morning, we walked a block to Standing Passengers coffee, the Breakfast House was a short walk for an amazing breakfast, and we ordered in dinner from Mana Food Bar and JJ's Thai and were super happy with both. The proximity to Family Dollar for groceries was appreciated as well.
This would also be a great place for families - there was a little playroom upstairs, and the roof top was totally safe.
The only thing that could possibly have been better was the water pressure. If you care about water pressure, you should know. But for us, when considering the fantastic location, the space, the amenities - we were supremely happy with this place.
