First of all we thank you for your appreciation on the authentic charm of this Provençal village house.
What is very unfortunate is that you did not know how to say to our faces when it was still possible to do what you wrote. We are very attentive and available as you can see and we have answered your many calls, trying to satisfy your requests each time.
Know that when you came to Provence in August you should expect to be warm. If the heat is difficult for you to bear, you must come to Provence in spring or autumn. Also, authentic stone houses whose charm you seem to appreciate are only very rarely equipped with air conditioning as they are in other countries. The Provençals do not need it because they know how to adopt common sense rules, which we communicated to you on your arrival to preserve the freshness and not to let in the heat which warms the houses until the end of the summer in an irreversible way. The same goes for mosquitoes, everyone in Provence is buying natural, harmless and inexpensive products from local supermarkets that keep these small animals increasingly present in our region away. You could have questioned us on this during your many calls. The dense vegetation to which you allude (I think you mean the plane mulberry, typically Provençal) is not intended to attract mosquitoes but to provide much needed shade and freshness.
To conclude, all this is only very subjective because the 4 German holidaymakers then the English family (see Ros's comments) who succeeded you in the same climatic conditions loved the place and already announced to us in their private Remarks that they intended to return.
This is all very relative. You may have simply been mistaken about the season or the region. We're sorry for your loss...
