It consists of several "cabins" or pods provided by Napcabs that you can rent by the hour (min. 2 hours, max. 12 hours) at 15 euros per hour, where you can relax and sleep while waiting for your flight.
The pods have air conditioning, alarm clock, internet access and flight information.
If you don't feel like getting one of these cabs, you can however rest and relax in a quiet area next to the cabins, with comfortable sofas and some electrical sockets where you can recharge your laptop or phone, but most importantly, there's absolute silence.
