Anoche fuimos a casa de Juan, y hablamos sobre su Turco amigo. We went to Juan's house last night and spoke about his Turkish friend.
Thank you

a LA casa ... su turco amigo
well done, just the article on 'house' ('la' casa) and nationalities take a small letter, unlike English
edit - see Franco's post - without the article is apparently fine, especially for friends houses, my apologies
Maybe it´s regional, but in Mexico it would sound very strange to say "Anoche fuimos a casa de Juan" without the article because omitting it means "my home."
When we say ie: "vamos a casa," we are saying "let´s go home" but to our home and nobody else´s.
a casa de Juan is fine. If he's a close friend, it's totally acceptable to leave out the article.
Y hablamos sobre su amigo turco (o su amigo de Turquía).
