Prior to arriving, communication with Bert was great and he was flexible with check in. Upon arrival, we were met by his partner, Clarine, who was extremely welcoming and friendly. In the place, we had everything we needed; it was clean, light, airy, and well-stocked for working at the table and cooking in the kitchen. While we were there, we couldn't have asked for more from Bert and Clarine. They were helpful, and gave us tips based on the interests we had listed on our profile (I very much enjoyed the dairy down the road).
As for Soest, we really loved it. We needed a respite from travelling and it was the ideal place to park up the car and ignore it for several days. There were enough museums, restaurants, and dunes (which I never really got my head around) to keep us happily occupied for the three days we were there.
I would sincerely recommend, and I hope we get the chance to return in the future.
