Supply is tight in Villanova sometimes, so it is more important to give yourself enough time to look than it is to focus your search at any specific point of the year. Give yourself eight weeks to complete the search so you aren't pressured, as it may take a little time to find an apartment that suits your needs.
Landlords in Villanova are used to dealing with tenants on a very personal basis.

If you want to live right in the Villanova area, you're probably going to want a car to navigate. However, if you're only travelling between major points, such as the University, you do have the access of public transit if you're willing to walk a little to get on a route. The University has public transit that shuttles people around campus, and you can also access the SEPTA train stations on campus, which will connect you Philadelphia, and throughout the region.
