Airbnb will offer three people and their guests a free, one night stay in an underwater bedroom in the shark tank of the Aquarium de Paris in April. The lucky few will be chosen through a competition on the accommodation site.

Airbnb's first underwater bedroom provides a 360-degree view of the tank with 35 sharks. In order to take part in the competition you have to write Airbnb and explain why you feel that you should be selected in 50 to 550 words. All contestants must be over 18 years of age.

Entries in the competition are due on April 3. The winners will get a night's stay between April 11 and 13.
