This property accommodated our group of 18 very well! The main floor was perfect for a crowd, with an extra large kitchen table; extra table for puzzles and games; sufficient plates, silverware, etc.; multiple seating areas; and spacious deck with lots of chairs and tables. The location was amazing, with a short walk down to a beautiful beach and an hour and 15 minutes to downtown Chicago. The main floor of the house was large, comfortable and modern, although the kitchen lacked a place to put dry food which was a little challenging. The upper floor was fine; bedrooms were basic and clean and the bathrooms were nicely done and modern. The bonus room above that was great for our teenagers and younger cousins! The spiral staircase to get up there is not for the faint of heart but the kids were not fazed in the slightest; if anything it added to the fun! The basement rooms were really just a place to rest at night, which was fine for our group because all of our waking hours were spent on the main floor, on the outdoor decks or on the beach! The basement rooms could use some sprucing up for sure, but I would say they are as advertised. If there was any downside to the house I would say that many in our party found their mattresses to be uncomfortable. Otherwise though we had an amazing time and would definitely come back if we lived closer! I will also mention that the owner/property manager (not sure who I was talking to) was extremely responsive and helpful!
