How to structure my site?

Hi all

I'm new to Drupal and trying to get my head around everything.

I'm building a rental site for rental properties but I'm sure how to organize it correctly.

What I need is this "structure" City->Area(s)->Rental(s)

I made "rental" a content type with all the relevant information (price, size, description, images etc.), but what is the best way to link these to an area, and several areas to a city?

(sorry if this question is in the wrong category, feel free to move it)
