Googlebot doesn't crawl the entire Page

Hello,

I discovered today that google does not crawl the entire page. (Fetch and Render)

I tried to figure it out why but I can’t.

Googlebot crawls 50-75% from the entire page, after that it stops and return successful.

Some examples:

https://grecia.de-weekend.ro/insula-santorini/

Anyone can help ?

Thanks,
Andrei
