We as the last reviewer stayed here to see the Puy Du Fou, which took us about an hour each way using the Peage.
La Roche Sur Yon is entirely forgetable, I wouldn't stay there just to stay there, if you know what I mean....
The hotel itself is absolutley fine, only complaint was that the room of our travelling companions smelt of smoke & was meant to be non-smoking.
The hotel has a restaurant which looks very good and didn't look overpriced, at least in comparison to the one we foolishly used just up the road! (can't remember the name of it, but out of the hotel, turn right about 150 yrds with a blue canopy; expensive, low quality food and they quite obviously don't like the English!)
There is secure 'NCP type' parking next door at €5.00 per day, and although you can only get access to your car up until 10.00pm, vehicular entry is permitted 24hrs, so a late return is no problem.
So in summary, good hotel (of type) offering average value in a non descript town.
