Thoroughly excellent apartment. Cannot fault our say.
We stayed for a week and it proved an excellent base for exploring all that Versailles has to offer.
Within very easy walking distance of the Palace, Cathedral, Amenities and Trains to Paris.
The only down side we could find is that it is way too close to a fantastic Creperie to be healthy :-)
Wonderful, cant recommend highly enough.

In attempt to experience la vie de France, my husband and I booked this Versailles apartment in between hotel stays in Paris. Truth be told, I had hesitations about going without hotel conveniences/staff, but these were unfounded. Not only was the apartment clean, comfortable and well-equipped, but the owner (Mr. Guillon) was available (though respectfully invisible) at all times to support us as needed. Actually, "available" doesn't do Mr. Guillon justice. In addition to the comprehensive notebook of area resources and tips (in 3 languages), Mr. Guillon gave us his mobile ph# and offered to rescue us if we ever lost our way during our stay. (Fortunately, we didn't need to take him up on this.) Mr. Guillon also graciously stored our luggage after we checked out, and he waited until late in the day to see us off and make sure that our taxi service was in order. Mind you, I don't think we came across as needy--I speak some French and we are middle-aged capable travelers--he is just an outstanding concierge.

The apartment itself is well-situated in the calm and welcoming quarter of St. Louis. We enjoyed the location because it is beautiful, residential and not in the midst of the tourist area, yet convenient to the palace, park, market, etc.

Cleverly and tastefully furnished, the apartment felt spacious, allowed us to unpack, do laundry, and feel at home.

In short, we highly recommend Les Carrés!
