Get DefaultAppPool AppData folder from the web application

Question

I have a web application which is running from DefaultAppPool account. I want to write some files into the DefaultAppPool's AppData folder (or any other folder, which is 100% accessible from the account my application is running)

I've tried

Environment.GetFolderPath(System.Environment.SpecialFolder.ApplicationData)

but for some reason, it returns an empty string.

Environment.GetFolderPath(System.Environment.SpecialFolder.UserProfile)

returns C:\\\\Users\\DefaultAppPool as expected.

How can I get the AppData path for DefaultAppPool?

EDIT: This code is executed in the Model
