A word of caution: if you plan to visit Paris or Versailles by public transport (not by car), this may be a bit difficult.
The air conditioning is very good - but I could not find a radiator. During cold days some may find heating by the airco unit unpleasant.
If you plan on going by car to Paris or Versailles, this is the place to stay! Excellent location, 20-25 minutes outside of Paris (trip duration to Tour Eiffel, even in heavy traffic), 12 minutes by car to Versailles. Prices during the week-end are half the prices during the week and you will not find anything like this for this kind of money in Paris. Free parking, large enough rooms, very clean, very good beds (both doubles and twins). We stayed with 3 adults and a child in 2 rooms. Good size bathroom, good shower. Very nice staff!
On south-west side of Paris, towards Versailles, in a very quiet suburb. It;s already my second stay there and I will come again.
