'cosy place' is the definition.
'berth' can be an answer for 'place' (synonyms). I'm unsure of the 'cosy' bit.

Can you help me to learn more?

(Other definitions for berth that I've seen before include "Bunk on ship or train" , "Bed; mooring" , "Place to sleep on a ship" , "Ship's bunk" , "Bed on a ship/train" .)

I've seen this clue in The Irish News.
