This is the 16404th most frequent Turkish word.
yatakları
"Yatakları" means "their beds" or "the beds" (depending on context).
Here, 'yatakları' refers to 'the beds', meaning the plural object (beds) in the accusative case, as it is the direct object of the verb 'bulmak' (to find).
Oteldeki yatakları çok rahat buldum.
I found the beds in the hotel very comfortable.
In this sentence, 'yatakları' again refers to 'the beds' in plural accusative case as the object of the action performed ('to clean').
Bütün yatakları temizledik.
We cleaned all of the beds.
Here, 'yatakları' represents 'the beds' in the accusative case, as it is the object that receives the liking described by the verb 'sevmek' (to like).
