I enjoyed our stay at Wolphus Farm in the Pigeonier. The owners are very amenable and friendly, and the gite, although needing a little renovation in the kitchen was perfect for our purposes. We travelled with our 3 month old, and i would say i wasn't confident with carrying her up the stairs as they are quite narrow but the OH had no problem. I also would say it is better for children who are a bit older, definitely not those which crawl due to the tiled floors and mezzanine level - there would be nothing stopping them crawling off, however 6 yrs + would be fine.
They have other properties more suitable for younger families or for people travelling in groups of more than 3.
