The waiting game...
So, now I wait some more. I'm waiting to see if I hear something from Strasbourg or Grenoble. The thing is that the schools are on vacation starting on July 15th, so if I want any info from the schools that I'll be going to, I have to email on Monday, or Tuesday morning at the latest.
I've found a possible place to stay in Lille, but I have to contact them and find out if they'll have room available. However, that would mean taking a train from Lille to the cities where the schools are.
