Stayed here for four nights in August with a 7.2m motorhome. We were able to move pitch to get two nights by the river - absolutely lovely in spite of a few midges. Reception was excellent and quick. Our pitches were large and gave maximum options for positioning for sun/shade but I agree some pitches did seem smaller (but people can ask to move and most people seemed to have an option especially if they arrived early). All pitches were pretty close to a water supply.  

Toilets/showers were clean (not the most modern, agree) and surprisingly never busy. I liked the fact that the camp site wasn't overly lit at night - as a consequence it was a great spot to star gaze. I would suggest adding more recycling and rubbish points as it's a long walk to the single facility.

Wifi was reasonably priced but only available in the reception area. Swimming pool, while small was good and clean and surprisingly not busy during some very hot days. Didn't try the food but the bar was a pleasant place to meet people and there were lots of books, games etc. to borrow. Great position for walking, cycling, chateau visiting, river swimming, canoeing as everyone has said and the staff team very willing to give advice and help with arrangements. Small supermarkets cycling distance but we needed to go with the motorhome to get more choice.

When I booked through CC I don't think a riverside pitch option was available - you seem to be able to get this only if you book direct.

It's one of the best Loire sites we've tried and I think we'll be regular visitors.
