He might look like hes 85, but Alfredo still keeps the spirit of a 20-something year old.
In a good way - the man has the optimism, energy and desire to meet new people.
Be careful, you might find your place cleaner than you left it if he stays there.
My only advise against hosting Alfredo is if you support one of his rival soccer teams - he might not buy you the first round.
