"i will not promote" An app idea for IT: The best cities in Poland for remote work

I plan to create an app that will help people working in IT find the best places in Poland to work remotely. The app is supposed to offer information on salaries, cost of living, quality of internet, availability of IT jobs, coworking spaces, technology communities and many other factors that can influence the decision of choosing a city to live and work in. I would like to know your opinion on this idea. What features would you find most useful in such an app? Do you think there is a demand for such a solution? Do you have experience with similar projects or apps? I look forward to your comments!
