Athletes can choose whether to stay at the Olympic village, which accommodates around 14,250 competitors at the Games.
Alonso had an underwhelming Olympics after finishing sixth in her heat — 0.24 seconds behind fifth-placed Georgia’s Ana Nizharadze — to miss out narrowly on the semi-finals.
She then dramatically announced her retirement but remained in Paris after her competition.
Alonso said: “Swimming: thank you for allowing me to dream, you taught me to fight, to try, perseverance, sacrifice, discipline and many more. I gave you part of my life and I don’t change it for anything in the world because I lived the best experiences of my life, you gave me thousands of joys, friends from other countries that I will always carry in my heart, unique opportunities. It’s not goodbye, it’s see you soon.”
The village is located on three sites across Paris’s northern suburbs, namely, Saint-Denis, Saint Ouen and L’Île-Saint-Denis.
Up to 60,000 meals are served each day across the sites, while a medical clinic is available at all times for the athletes.
