As the owner was not able to receive us, we had to discover the house on our own. We had adequate telephone assistance to get the key and deactivate the alarm, but showing us around at arrival would have been nice. That way we wouldn't have been surprised by an active alarm on the swimming pool. The house was exactly how it is described on the web, airco working properly (only one in the bedroom making some really strange noise), wifi working great, swimming pool okay, two nice bathrooms, ... Cleaning could have been more thorough. Possible improvements: put a shower hose on the bathtub upstairs, connect the extraction above the cooking plate to outside (now it is blowing in the house, so pretty useless), close the numerous cracks and holes around the doors/windows as they are entering places for ants. Summer visitors should be aware that the house is surrounded by trees, insects are never far away (wasps, ants, musquitos).
Despite some of the above mentioned issues we experienced, we had a good time in Grignan. The owner gave us some nice ideas on locations to visit (tapas restaurant in St-Restitut was great!) and was always available when needed.
