France - Nimes - luggage storage?

Hi, since the train station does not have a left luggage facility, does anyone have a recommendation on where my daughter and friends could leave their backpacks while they tour the city? They are taking a train from Barcelona on their way to Arles, stopping in Nimes for the afternoon.
I've emailed a few hotels, no luck so far.
Thank you!

Posting reply for next person in same situation - my daughter found a hotel that would take their luggage after an hour of looking...unfortunately she doesn't know the name - she said it had a blue sign that simply said 'hotel'. If I get a name, I will post it.
