I was looking for someone to have some spanish conversation classes with. I happened to find Marina which turned out to be perfect for me because a) she was capable of adjustments in accordance with my needs, b) has been really flexible time-wise, c) she was willing to show me around the city during the classes and most importantly d) I found it very easy to talk to her just about anything... And she was patiently listening to my miserably constructed sentences in order to improve me afterwards :-).
