This is a very small family run Hotel, personally I would class it more as a Boutique B&B than Hotel, as such I didn't find the locked door mentioned in other reviews an issue (guests can use a key).
Having booked on the day we had to change rooms after the first night (which we knew at the time of booking). La Villa de l'Etang blanc only has about 8 rooms which all seem to be individually and very lovingly decorated. Both rooms I stayed in had an en-suite bathroom and small chill out area with a sofa.
The Hotel is very remote and sleepy with absolutely stunning grounds.
Continental breakfast is fresh and served in the beautiful restaurant. Having stayed there with friends I mainly used the Hotel as a base but nevertheless had a very relaxing stay and could definitely imagine going back to, I'd recommend it for couples.
