Tour template changes

How do I change the layout of the individual tours so I can put different elements in them.
My use case:
I want to change the image on the left to be small, maybe half of it’s current styling.
I have condominiums which include apartments which I need to be displayed in the Condominiums page but the element should only exist on Condominiums (like recently viewed). How do I link products and how do I add them to each others page? How do I hide the price of Condominiums only as only the apartments’ prices should be shown? When I set no price to a product the website’s front end brakes.

You will need to customize the design of the templates for these pages. Unfortunately we do not provide theme customization services, and you will need to hire WordPress Developer via fiverr to do these customizations for you. Thank you.

Where are these templates located?
