I will be moving to Paris in January for work. I have a one-year contract and I'm looking for a place near Montparnasse, but I'm flexible. I'd like to be close enough to the centre, but I will be commuting to Vanves to work. Really, anything south of the centre but inside the Blvd périphérique works for me.
My maximum budget is €500 per month, and I'm looking for about 15 m2. I can deal with a WC sur palier :)
