24 year research student looking for a affordable stay in paris

I am a Nuclear Engineer - research student from India, pursung my doctorate in CEA, Saclay. The course is for 3 years and I am looking for a suitabe place keeping in mind the budget constraints. An apatmnt or studio can suit my requiremts. I prefer student rooms rented by family. I am a very homely person and love to dpend time with kids and childen. I am good at teaching and can explain the toughest problems in simplest manner. I have been in France for an year and I like the culture here. I can undertand the language and speak good too. I am fluent in english and I am a good cook too. It would be fun to spend time with a family during my stay and make good friends. 

I will be moving to Paris from Avignon on 15 september.  Do not hesitate to contact  or ask me for further information.
