Considering the Citotel Criden in Tours?

Chateau de Chenonceau by K1W1
This place is like it has been created from a fairytale. The castle, moat and grounds are in impeccable condition and it would rate as one of the most impressive castles I've seen in Europe. I would love to have seen it at night with the flood lights on it. It took just under an hour and a half to reach by bike from Tours and was easy to find.
