Φτου, so many Italian and French loanwords in this topic...
How about: ..."Η σοφίτα 'εχει μια τουαλέτα"?
Hm. It's already a possible translation, but there seems to be a problem with μια, without an accent. Which is a bit odd. I'll try to fix this, thank you for your comment ^.^
τουαλέτα should also translate to "loo", right?
