Build me a full stack travel listings app like Airbnb called Wanderlust.

I want users to be able to sign up, log in, browse places to stay, view a listing page with photos, a map, details, and reviews, then create, edit, and delete their own listings. Logged in users should also be able to leave reviews, and only the owner should be able to change or remove their own content. Please include flash messages, server side validation, and good error handling.

Use a clean responsive design with a modern look, and make it feel polished on mobile and desktop. I also want image uploads for listings, saved in the cloud, and location data shown on a map. Keep it organized in a simple MVC style with views, routes, controllers, and models.

If you need to look up the current docs for anything like map or cloud image setup, do that. Make it work end to end with a local setup and easy environment variable config.
