Its always the same in new airports. It's actually a 20 minute turnaround door to door, with the 5 mins for the F/D to do their final checks and call for clearance.
Unless the handling agent preboards PAX as the A/C pulls onstand, it's very difficult to achieve. Although it is regularly achieved in all aiports (well, maybe not Italy!!) and is doable, but it takes some getting used to! Preparation is key, with the PAX assebled -40 and pre Q checks done in the 15 minutes before the A/C is due onstand.
