Student rental amenities

[Jeremy Fields]

I've got several rentals in an area that is predominantly occupied by students and would like to offer the most desirable products in the area. One of our units is a 5 bed home that will be renovated next summer and split into 3 apartments. The plan is to have (2) 3 bed/2bath and (1) 1bed/1bath. 

Looking for advice:

What amenities do students desire most? Which are a waste of money?
