Help: TU Delft

Hi everybody!
I´m not an active poster to this forum, this time I´m asking for some info.

I´m studying Aeronautical Engineering in Madrid, and I´m in my fourth year now. I´ve the option of spending one year studying abroad, under the ERASMUS programm. I really like Holland, and TU Delft is a good place for aeronautics so I´ve chosen Delft as my objective. My main problem is the lenguage, I´ve some info about english classes in the aerospace engineering faculty, but I don´t know if ALL classes are taught in english. Of course, learning Dutch in just 4 months is not a very good option.
So… anyone here studying in Delft?
How is it? Not only the lenguage but the place, the people….

Regards

Jorge
