"These living rooms are very modern and pretty."
Translation:Estas salas son muy modernas y bonitas.
I find the word 'pretty' very awkward and out of fashion in English. As I mentioned previously, I don't see it being used anymore in books, magazine, TV, movies. In my view, I can only see it being used about contestants in "Toddlers and Tiaras", and even then, it seems inappropriate.
