We spent a wonderful 10-day holiday at Gite de Bonneuil earlier in the year.
The property has been refurbished beautifully (probably fairly recently - everything feels very modern) and to an extremely high standard. The house is very spacious - we had 6 adults and 3 children in our party, and had masses of space. The kitchen is well kitted-out, with 2 dishwashers, a huge fridge and a huge freezer. The big dining table gave us lots of room and the open-plan layout downstairs worked well for a large party. The master bedroom is incredibly impressive and the other bedrooms are also well-appointed.
Outside, the garden is pretty and the surrounding fields create a very peaceful environment. The pool is heated and large (though note you need to start heating it a few hours in advance if you want it at max temperature), with lots of loungers and pool toys. And there are facilities to eat in the sun or shade. The children's play equipment was also a big hit - with a slide and two swings. We spent a number of enjoyable days around the pool/outside area, with no need to go further afield.
Both the owner and housekeeper are incredibly helpful, answering numerous questions for us and providing useful information.
We found the location to be great - with a big supermarket within a 15-minute drive, plus markets, chateaux and restaurants all within reasonably close proximity.
The only complaints from us were that there were a lot of flies (though there are some swatters to help keep them under control) and some kitchen items were slightly lacking (could do with more glasses and tea/coffee mugs, for example). But very minor stuff.
Overall I would thoroughly recommend Gite de Bonneuil for a family/group holiday.
