I've recently been hired as an ESL teacher in a holiday camp in France for a period of at least 5 weeks. So, I would prefer to sublet the room to someone who wants to spend over 5 weeks in Paris.
The double room (10m2) is in a charming & secure 2-bed apartment of 50m2 in the 17th district. Close to many touristic sites & well connected with other parts of Paris.
ps- you'll have a female flatmate in the last months of her thesis!
pps - prices will be negotiable
