We have a cottage in the chateau grounds which we use as our base. We don’t rent it independently of the chateau, but for weddings we can rent out two double bedrooms with en-suite bathrooms, and a further small double bedroom. This is on a bed-only basis.
If you need a few extra beds for wedding guests then the cottage may be just the thing. It’s only a short walk from the chateau. It could also serve as perfect accommodation for a small team of cooks or drivers if you have them with you.
