[French courses]

Could anyone recommend a good language school in Paris? I am currently working so I'd prefer something that you could do on week nights or just the weekend (rather than an intensive course). Thanks for your help!

Another option is to try a ridesharing platform like http://www.carpooling.fr/

By taking paying passengers you can save money on petrol and reduce the costs of renting a car. I have done it in the past - you can have a lot of fun!
