How do you describe, using a noun, a place you can escape from your old life but only temporarily. It kinda feels like a summer house, but bears no relevance to the seasons. I have thought about the word 'seclusion' but it seems to have nothing to do with a place, rather more like a state.
I suggest hideaway about which the Oxford Dictionary has
A place used for hiding in or as a retreat from other people.
‘Little Cayman has to be one of the most peaceful hideaways in the Caribbean.’
‘Very young children often have secret hideaways where they go to seek solitude.’
‘I love the way the topography lends itself to creating secret hideaways where guests can sit down and enjoy the views in seclusion.’
In the States, a getaway TFD
- a place where one escapes for relaxation
- a period of time for such recreation.
I need to get to my getaway for awhile to relax and be away from the rat race.
Such places are commonly called retreats as mentioned in the comment. This noun is in a neutral register, whereas hideaway and getaway are informal.
Camp David is the country retreat for the President of the United States.
Neither of those informal words could be substituted here without a register-clash:
Brokered by U.S. President Jimmy Carter between Israeli Prime Minister Menachem Begin and Egyptian President Anwar el-Sādāt and officially titled the “Framework for Peace in the Middle East,” the agreements became known as the Camp David Accords because the negotiations took place at the U.S. presidential
