We visited La Bernerie for a week at the end of October and had the most wonderful week.
After a long, wet and delayed journey we arrived to a lovely warm gite, Roland met us and explained how everything worked and then we explored. The kids absolutely loved the games room, which was a godsend, they got up early and played and went in there every evening whilst I was preparing dinner, with family competitions after - brilliant fun!
Roland kept the pool heated for us too, it was much warmer in the water than outside and the kids loved it. I can imagine in summer it is an amazing place to relax.
Whilst in the area we visited the Marais Poitevin, the Mervent Vouvant forest and Puy du Fou - all within an hours' drive maximum. The Grand Parc, Puy du Fou is something else! I know we were lucky because it was end of season and a cold wet day so we didn't have to queue and saw a lot, but the shows were extraordinary and if you are in the area it is a must.
The gite is very rural, so peaceful is an understatement, it is pitch black at night so take a torch if you want to go outside. It is a fantastic place to escape from the hustle and bustle, there is everything you need, including good wifi and English satellite TV, a filter coffee machine etc, but it's not full of mod-cons, it's exactly what you should expect from a beautiful rural holiday home.
