London to Paris: Route Advice

We're going to Paris and back on the bike, does anyone know a good place to stay in Paris that allow us to keep our bike indoor and reasonably priced?

We stayed at the Formula 1 in the north of Paris, they let us put the bikes in the luggage room for 5 Euros. Only the receptionist has a key, and they let us lock the bikes in the room so it's fairly secure.
The hotel is ok if you just want somewhere to sleep and shower, not if you're looking for a good breakfast!
