We had a brilliant time in and around the farm- definitely a unique experience. The cabin was compact but had everything we needed and the bathroom and shower facilities in particular were very clean and fresh (much better than we had expected). Breakfast was lovely. We would've found it useful to know that, in the absence of a car, you are very reliant on cycling to get about on this holiday. There were some (old but workable) bikes available on the farm and we had a great time on them, exploring the little villages nearby, but we are not very hardy and, had the weather been poor, this could have affected us badly.
Also useful to note that the villages nearby are v rural so nothing really open on a sunday (and actually many places were also closed on mondays and tuesdays), so wed-sat probably a better time to book here, although pretty close to Amsterdam so you would never be stuck (especially if a more confident cyclist). Last tip- if arriving in the afternoon/evening, arrive with food as there's little available in the immediate vicinity (esp. without cycling out).
Altogether a different, exciting, and memorable holiday. Would definitely recommend!
