'I love sex. I like to make money': What sex workers really want
Dark walls, with vibrant patterns in certain places, and a dark ceiling surround a dark bed coated in a protective sheet. A mirror the size of the bed lines the wall adjacent to it.
A large bath sits in the middle of the room, with a sink nearby, and a tall red chair sits prominently in the corner.
The room mirrors many in the De Wallen region in central Amsterdam, home to the city's red light district, with this one regularly rented by a woman who uses the name Foxxy Angel professionally.
She rents the room, often referred to as a window, from the Dutch sex workers collective My Red Light.
The 37-year-old sex worker can be found here during the day, ready for clients, usually tourists.
A pull of the curtain string is all it takes to reveal the heaving crowds on the streets outside and to indicate that the room is open for business.
"I love sex. I like to make money," said Angel, who has been in the business for more than 15 years. "I've had a lot of different jobs before, and this is the only one I really liked."
Her window rent costs €80 a day, she explained, and she typically sees five or six clients per day, making at least €50 per client. When her shift ends, she also sees clients in bars or clubs and goes on location for larger group experiences.
Her hours are her own, and she reports only to herself.
"After 15 years, I'm still enjoying it every day," she said. But she's set an age limit of 45 before she moves on to focus more on her advocacy work, fighting for sex workers' rights; she's an ardent member of the Dutch Union of Sex Workers, also known as PROUD.
She's fighting because Amsterdam, she said, isn't as liberal for sex workers as many believe.
Sex work has been legal in some form in the Netherlands since 1830, but it was recognized as a legal profession in 1988. In 2000, a law made the job subject to municipal regulation, requiring a license to operate and following certain rules set by a municipality.
Being a sex worker is legal in licensed areas, Angel explained. "We have to follow all these rules, and these rules don't guarantee our safety," she said, giving an example of how increased regulation and legalization bring police and municipality checks, which often stop clients from coming in.
