We had a lovely stay. The hosts were very, very responsive to all our questions and needs throughout the stay, but they also gave us our own space and privacy to relax (the perfect combo if attentiveness and privacy). The space is beautiful with amazing wood floors, new kitchen with anything you'd need, a spacious sitting area, and a very cool shower. We also enjoyed exploring what their property has to offer. (They are working on some new features that I expect will be awesome when finished!)
A couple of things to note for your planning as a guest, there is only one queen sized bed (which was very comfortable), so if you have more than two in your party, plan to use the couch and the cot. If you have a picky back, consider bringing your own air mattress or something you know you like, as the cot didn't cut it for my kiddos.
Also note that the family lives upstairs (with young ones) and you will hear them walking above you throughout your stay, so if you want to feel alone and have total silence, maybe this is not the retreat house for you. But if you don't mind happy family-life noises above your head, then you'll love your stay; the place was full of love and warmth.
