There is a
Youth Hostel at Porte de Pantin which is very convenient for the canal and for getting in to and out of Paris easily. Directions are on the map below (the blue line). The hostel has the advantages of being very cheap, having a proper lock-up garage for the bike, and big showers with room to sort out all your stuff and get cleaned up. It has the disadvantages of being pretty basic, with shared rooms and no real privacy and possibly being noisy, depending on how many gigantic groups are staying at the time.
If you're travelling on your own it's fine for a few days (you can only stay 6 nights anyway). There are large coin operated lockers where you can leave all your stuff while you go out. They cost 2 euros for 24hrs. There is also a launderette just round the corner which is really easy to use. You should be a member of
the YHA (or your own country's Youth Hostelling Association), but non-members can still stay there for a small extra cost.
If you don't fancy the Youth Hostel then there are several large hotels around Porte de Pantin (Libertel, Holiday Inn, Mercure etc), and millions of other places in Paris itself.
