Excelente profesor, siempre prepara material relacionado con mi profesión para poder trabajar sobre ello en clase, lo cual me permite mas agilidad en mi día a día. Clases muy dinámicas tratando todo tipo de temas. Muy muy recomendable

Súper dinámico, se adapta a tus necesidades y siempre se presenta con una sonrisa en la cara. Un gustazo de profesor.

Rafael is a great tutor, very patient, he suits his teaching to a student - which is great, having in mind that some people are afraid that they won't be able to speak only in english, like myself. He shares a lot of intersting way of learning english, both spoken english and grammar, vocabulary. He is very interesing guy, and any casual conversation was also great to had with him. I have improved my spoken english vastly and that was my goal. Highly reccomended.
