Best Fridge for a weekend home(high humidity, near sea)

I have a weekend home by the sea and there's very high humidity. I want a single door fridge, i don't care about stars really as it will be used for 4 days in a month max. It's should be reliable as there are not many good repair shops near there and no rusting. Will there be good freezing in the small freezer you get in a single door fridge? It should ideally be under 15k
