First off, Nancy and Lon (the owners) were beyond kind and helpful. Lon took us on a personal tour of the house, and told us all about its history. Nancy shared produce from her garden as well as some ingredients we needed.
The house is furnished with antiques, and is very old. One of my daughters was over the moon with all the furnishings, dishes, it's location in the country, etc. Another daughter was bugged by the squeaky floors, spiders, inconvenient light switches, lack of a dishwasher, and lack of wifi.
So it depends on what type of person you are. Personally I thought it was wonderful for a few days, I enjoyed the distraction-free time with my family, and loved sitting on the swing in the front yard at night watching the fireflies.
Just a few things I wish I had known-- there is wifi, but it is pretty spotty. I was never able to connect. There is no grocery store in town. The closest store is 20+ minutes away. And there are a few dining options in town, but not many. So bring everything you need. There is a Walmart in Keokuk, about 30 minutes away. There is no dishwasher, so bring paper products or be prepared to wash all your dishes by hand. There is a place in town that does takeout pizza that's supposedly good. We heard that cell phone coverage is spotty unless you have Verizon (which we do, and we never had a problem).
