In 'Lady Behave: A guide to modern manners' (written in 1956) they have a lovely piece of advice on how to word a personal advertisement in the paper. This one is for 'a flat and a job' and goes like this:
'Young couple require flat or similar accommodation in London end of October, while finishing his medical training. Wife will give services during the day. ...'
I would imagine that despite the current cost of accommodation in London they would get plenty of offers for this today..although I don't think that 'Caretaker, receptionist, housework or cooking' would be what they would be expecting in the way of services!
