Summary

I can't create the website or generate the code to host it (such as a "Homes and Apartments for sale" database or an AI App Store) in a single response.

Why:
The information you have provided (title listing) appears to be a product name, business category, or trade catalog. However, I don't know what you do exactly:

1. Do you want a structure for your website ("Landing Page") that contains all these options?
2. Do you want a functional website that connects all these offers in one place (for example: "Here is my list of offers in Madrid").
3. Do you have a domain (e.g. `www.madridresales.com`) and need hosting and server?
4. Do you have a mobile or web app specific to AI and you want me to generate the design and code for it?
5. Do you need a plan or a business model (Business Model Canvas) to sell this type of real estate and AI?

### Option A: I generate the Code / Website Structure

I'll assume you're a professional who wants a modern, responsive landing page to present this type of business. Here is a template that includes all the options you listed.

I have used HTML5 and modern CSS3. You can copy this code, save it as `index.html` and open it in your browser.
