Airbnb is out with a breath-taking promo - sleep with the sharks! Airbnb is providing three people along with their guests a night's stay inside the shark tank of Aquarium de Paris in April for free. Prospective guests just need to send information why they should be the lucky one to have this exhilarating experience.

The rental sharing website already offers night stay in converted planes, cable cars and Ikea as publicity stunts but this is something that anyone should not miss - underwater offer and sleeping with the sea predators.

The 'underwater bedroom' is surrounded by a 360° clear wall which is the only thing that separates the guests from the 35 sharks. The room lies in three million liters of water inside the tank where the host Fred Buyle, a world record-breaking freediver, shark conservationist and underwater photographer will welcome two people. He will provide a guided tour inside the aquarium and educate them about how sharks live and their importance to the ocean's ecosystem, as reported by the Independent.

"We're thrilled to be the first Aquarium in the World to offer this chance for people to be more than simply visitors, but to get such an 'immersive' experience," said Alexis L. Powilewicz, CEO of Aquarium de Paris.

Liligo.com reports that the Aquarium de Paris is located in front of the Eiffel tower. It will host its very first sleepover from April 11 to 13 in their shark tank. Airbnb will shoulder your flight expenses as well as your guests.

To qualify for the said promotion, contestants should be over 18 years of age, medically fit with weight not exceeding 190 kg to easily climb in and out of the bedroom.  They also need to write information about themselves not exceeding 550 words including the main reason why they deserve to sleep beside the sharks. Entries should be submitted by April 3 at 11:59 PM CET, according to Business Insider.

Guests are reminded not to take selfies after dark as sharks are sensitive to light and heads and feet must be kept into the bedroom always. They will also be treated to dinner with amazing tankside views. This is once in a lifetime opportunity that adventurers should not miss.
