I did not (yet) rent any other Chateaux so far, so I can not compare to other alternatives, I can say though, that I did a long online research of many other similar offerings, but none of them could accommodate groups up to 18, plus have the breakfast included in the rental price.
We (a family of 14, including 2 elderly, 3 couples, 6 children and teenagers) spent a lovely 10 days at this beautiful chateaux. The place is impeccably maintained, FULY equipped (wifi, ping pong, pool, outdoor equipment, 20 bicycles, BBQ, very tasteful furniture and decoration, fully equipped kitchen, even including a black swan and geese who swim in the lake and moat around the house:)
We really felt like French novelty, with a great breakfast, including fresh baguettes and croissants every morning. The house keeper is incredibly nice, and makes all efforts to accommodate every need. When suggested to take her home with us, it appeared that many guests before us had the same idea...this lady works at the house for 34 years, and one can see her care an love to the place in every corner (and there are many, as the house is big). she makes a real difference.
The location is very convenient, 2.5 h drive from Paris, 20 min from Le Mans, surrounded by lovely villages, restaurants, supermarkets 5 min away, and would be a great base for Loire Valley explorations.
Booking arrangements and communications with owner are very effective and pleasant.
Dearly, dearly recommended. A+++
