I've stayed there while attending an event in the neighborhood. It is a nice country hotel. We had a very spacious room, well maintained and clean. It was located in the building next to the main one. The hotel has a big own parking lot, so going by car there is not a problem. My advice - take the option with breakfast! The choice was large and abundant, with a lot of fresh produce, practically there was everything you could think of. I was pretty surprised how lively this place is on the weekend! The large terrace was crowded the whole day.
You won't be mistaken if you chose to dine in the restaurant as well. Good food and fair prices. You have the choice between a regular size meal or a ladies/senior size, which is quite nice if you want to enjoy a three course meal and not feel completely stuffed at the end, or if you are sensitive about your weight... And what you should really, really try is the macaron with raspberries (macaron framboos). It is yammie, it is clever, it is sensational! I would return there only for this dessert!
In a nutshell - if you happen to be in the area or if you are a nature-lover, De Vossenberg won't disappoint you, on the contrary - it will surprise you!
