The room seen on the frigate was the dining quarters. A sober space with metal benches without backrests. A series of small plastic fans were mounted on the walls. This is usually not necessary with properly functioning air conditioning. The hallways were also empty, plain and bare except for some framed glowing posters. It did not look modern and advanced, although at the time this was a completely new series of frigates.
There were cables visible under the ceilings, but no network cabinets, switch cabinets, computers, WiFi transmitters, etc. as seen on Dutch ships. There were also no fire extinguishers visible. Possibly all the previous work was done, but that chance does not seem great.
All in all, the frigate did not make an advanced nor robust impression.
