We were happily surprised with this experience. The girl that introduced the farm to us (Victoria?) when we arrived was lovely and very helpful. The caravan was brilliant and very well equipped. We stayed with our kids (8 & 11) and they loved it. The facilities are excellent, there are showers, toilets, hairdryer (!), a common room with a Nespresso machine(!) and a room full of anything you may have forgotten and also a fridge where you can keep your stuff. All very clean, all very well thought.
The caravan was comfortable and the duvets kept us warm, the main challenge is when someone sleeping at the back needs to go to the toilet (the only way is to crawl over who is sleeping at the front) but this is part of the adventure!
