Welcome to the documentary from the BBC World Service.
I am Carmen Mohamedi and I'm here in the Italian city of Florence, one of the world's most popular tourist destinations and my home.
I'm sitting in the sun outside a cafe in Via di San Nicolo, a small street just outside the city centre.
I'm here to tell the story of how new technologies and hypertourism together have profoundly changed the character of this street over the last 10 years or so, and to find out what we might do about it.
That's why we've called this episode the street that Teck Built.
It was like being part of an amazing sculpture.
People really have this fear of missing out.
What changed was that Google Maps sent them that way.
I've lived in Florence for 16 years now, and when I first moved here, this cafe was just across the street from my apartment.
And it was here that I would sit every morning and I would work on my first book and I would watch local life unfold around me.
I met all of the street's characters and this is where I too started to become a part of the fabric of the street.
But now all I can see and what you can hear are literally thousands of tourists.
In the morning, like at 3:00, I used to wake up and walk in the streets and it was like being part of an amazing sculpture.
It was amazing.
It was such a beautiful thing.
This is my friend and neighbour, Giuseppe.
He was born and raised in Florence, then went away to university in the States.
And when he returned, he found himself marveling anew, not just at the city's beauty, but at its rather special creative magic.
For an artist, every shape, every form, somehow talking to you in a total silence, that was the best, probably the best, Florence I ever experienced in my life.
