Hi and Welcome,
If cost is not a factor then I would recommend Zamalek, lots of expats so you can get most things there. The area is full of cafes, restaurants, bars, clubs, art galleries and yet if you are in the right area it has a village feel. This is of course if you are attending the downtown campus.
Taxi is the common mode of transport and they are cheap cheap cheap, if you like the smell of B.O then bus is fine.
