I'm an Austrian student currently doing his PhD at CERN in Geneva.
Dinyar is very polite & seems like a nice person. I didn't see much of him since he was off to a conference where they must have fed him too since he didn't have breakfast :( Maybe he'll be back sometime, and I can make it up to him :)
Same feedback as stated previously (2nd of 2 separate stays in the course of 1 week).
Very nice, friendly, courteous guy. Enjoyed having him in my home.
