I've been having Spanish conversation classes with Lilian via Skype for over a year now to keep my Spanish sharp. She is very intelligent, having enough knowledge to talk about almost any subject. She's polite, well-traveled, outgoing, and loves to share fun stories of her life and hearing your own stories, making her classes fun and dynamic. Lilian also has formal knowledge of the grammar of both Spanish and English and is able to explain grammatical points when needed, and even offers remarks about her own word choices after telling a story (e.g. why she chose to use that specific verb tense, etc.). A great teacher overall.
