Hi Lukas,
You can design the system accommodation type pages with Elementor:
1. Enable the Developer mode in Accommodation > Settings (Template Mode).
2. Enable Elementor for Accommodation Types in the Elementor tab > Settings.
3. Open an accommodation type with Elementor and in Settings (left menu, bottom) select the Layout as Elementor Full Width.
This will give you an empty accommodation type page, where you can add the system elements however you want with Elementor (tutorial).
