There are some words that estate agents just cannot bring themselves to say.
"Terrace" conjures up images of dowdy working class people, mews sounds so much nicer, and more bohemian.
Other examples are "flat" which sounds a bit 1970s and must now be rebranded "apartment", preferrably with the adjective "luxury" or "executive" alongside. Bedsits (sounds like lino and gas ring in the corner) went out long ago of course, to be replaced with studios (arty, spacious). "Basement flat" is absolutely out of the question, sounds like a cellar, you must say "garden apartment" even if the garden belongs to the people upstairs. In fact suggesting that you're going to see a "house" at all is irredeemably vulgar, viewing a "property" makes you sound so much more astute.
One of the worst examples was an agent I saw who simply could not bring themselves to say a word so stark and common as "in", eg "a flat IN a victorian house". Everything on their list (sorry, brochure) was "set within the confines of", it was quite surreal.
Someone needs to write a piece of java code to translate this stuff.
