The 6.5 hour trip (with 30 mins break) was smooth and was some 12 mins ahead of schedule!
I was sitting next to a nice French guy called Aurel. He visits his girlfriend in Paris, but he plays with his band in Rennes. He tried to tease me asking if I speak Spanish, and we ended up talking in Spanish.
After knowing that I was still looking for a place to stay Saturday night, Aurel gave me his address, phone number, email and FB LOL
I am seriously considering Aurel as a backup plan, since I am still wary about my current Couchsurfing host, but I don’t know who’s more trustworthy XD
