This is an expensive two-star hotel! (Keep reading).
To be completely fair, I just want to state that the rooms were quite nice, clean (although the ensuite loo wasn't - but we kept the door shut), the separate shower-room was small/adequate, our room was pleasant and the bed was extremely comfortable, and although the location took a few minutes walk from the station, it wasn't an exhausting distance with wheelie-cases. Floors could have done with a bit of a hoover, but generally okay. There isn't a lift to the upper floors, just the main spiral staircase.
Mark on reception was a lovely fellow, very helpful and knowledgeable about his city.

However......
We paid the equivalent of £8-10 extra for breakfast per person - the equivalent of just less than £100 extra per day for all of us, in addition to the (rather expensive) room rates - and what did we get?? :

ONE stale croissant, and a VERY NASTY woman who took my kids breakfast away from them after they had only had one bread roll, and refused point blank to let them (or us) have anything more!
Both my children are well behaved, well travelled and quiet kids, despite having learning difficulties and other health issues. My eldest child has a food allergy that means he can't eat dairy-type food such as milk or cheese.
And that is all there was: packet cereal, jam, a portion of cheese, a yogurt, plus some (stale) bread on a plate.

This nasty woman actually stood over my boy and demanded in staccato French he eat cereal instead - she was even COUNTING the number of bread rolls consumed by each guest!!
She watched you from the doorway, and waited to pounce.

If she suspected a guest - who had, lets not forget, PAID in advance for breakfast - had consumed more than two bread rolls or pain-au-chocolat each, she would keep returning to the dining room and removing the plate with the rolls on it, deliberately preventing guests from having anything more to eat.
We had to continually ask for the bread to be brought back - which she did with very bad grace.
(It was like a scene out of Charles Dickens!).

Then she was nasty because my little boy had a second small glass of orange juice to wash down his single bread roll. Neither of my children can drink tea or coffee, which was the only alternative.

Apparently, the locals told us, this woman lodges at the back of the hotel and is not even officially a staff member, 'working' illegally and not paying Government employment taxes, etc - which may or may not be so, who knows?
Whatever the fiscal situation, I have never, in many years of national and international travel with my children, EVER encountered a more unpleasant, wilfully unreasonable and nasty person as this female!

The other staff took pity on us and were actually sneaking morsels of food from the kitchen hoping she wouldn't see, so that the children could have something to eat to start the day! But we had PAID for breakfasts that we didn't get.
It might have been funny, if it hadn't been so bizarre, outrageous and upsetting.
My young son is usually a happy-go-lucky, smiling kid, but she frightened him and reduced him to tears.

So, by all means, if you want pleasant accommodation - rooms only - near the centre of Versailles, this hotel is fine for that. But under no circumstances take any children, family or friends there, and certainly do not pay this hotel for food - eat out! There are several good eateries nearby, all within strolling distance.

Finally, I just want to say, I do hope that this weird person has since been removed from the hotel before your visit. Because frankly, no-one, especially no paying guest, should be put through the nastiness, and extraordinary downright meanness, we were mistreated to by this 'non'-employee.
(Pun intended).

None of our group would choose to stay there again, though.
Good luck to you if you do!
