It is never too late, everyone has their own life and occupations and even their own moment of disconnection. I have known Madrid for many years and I am of the opinion that years ago it would have been a great time to live it. Now it has become just another city, a city for tourists. The cinemas on Gran Via are gone, the most typical taverns and bars are now Starbucks or similar things. Sure, there are still things left, the Retiro Park in autumn or the Prado Museum, but it is not the Madrid I knew.
I'm talking about Madrid, from the rest of Spain there are still places worth visiting.
Anyway, if someday you visit us in Madrid you will be very welcome.
Best regards. 🤗
