From Julien, who asked me if I could relay this info on PDP:
We (the organizers of Planet, a congress for students and young professionals in urban planning around the world) have booked too many beds in the Paris International Accommodation Centre, a comfortable youth hostel located at Boulevard Kellermann near the Metro station Porte d'Italie and the Bus line P.C. (Petite Ceinture).
This Centre is surrounded by a garden and has parking facilities for buses and cars.
We have 9 double bedrooms (2 beds), with shower and private bathroom available at a very reasonnable price (135 euros for the 3 nights, instead of 150 euros) - Click here for more info.
For more information, please contact Anne-Laure at firstname.lastname@example.org
Enjoy your stay in Paris!
