My info dates a bit as I was there 12 months ago for two nights. We had a choice of rooms, so we took one with a balcony and it was quite spacious by french standards. The hotel in general was a very nice experience, especially the breakfast in the garden. Unless you are traveling with an unreasonable amount of luggage, you should be fine, but just to make sure, just ask them to have a look at a JS when you arrive. If they are not fully booked, they will let you see every room available, but I would not push too far.
