Your letter should be brief and to the point. (Is this something you'll be sending via email, or snail mail?) Simply state that in response to their advertisement, you would like to submit your resume (or CV) and be considered for the position. Then you'd either paste your CV in the body of the email or attach it (depending upon what Berlitz prefers).
