Not that I noticed it is a very small airport, a handful of gates, 1 duty free shop and 1 cafe. The lounges on the lower level.
However most of the hotels will give you a day pass to the pool and store your luggage after check-out and the pool areas all have shower facilities.
At Sofitel Denaru I had a midday check-out, but was given access to the pool (including the free nibbles and happy hour) until 6pm was able to freshen up before getting my uber to the airport.
