Need a secure car park near centre of Paris for car with bike rack

[Johnb0y]

We're planning on spending 5 or 6 hours in the centre of Paris on our way back from a camping trip in June.
Does anyone know of a secure car park where we can leave our car and bikes?
Preferably close ish to the centre of the city as we want to try and see as many sights as possible.
Thanks

We stayed near the Notre Dame (on other side of the river) in St Germain, and left our car in an underground car park for 3 days. Pretty sure it was short or long-stay.

Anyway, it was open 24/7 and manned. I can dig out the address if you need it, or google Neoparking.

This was it. Very central, quick walk over the river to Notre Dame, and we pre-booked our space to save time.
