Casco Antiguo Spanish School

A great place to learn or improve your Spanish skills. They really focus on listening and verbal skills. By the end of my 5 weeks I had advanced significantly in comprehension and speaking.
There is much to see and do in the Casco Viejo area in addition to the after school activities organized by the school. The Amadore Causeway is a great place to watch ships enter/exit the canal. Rent a bike on Sundays and ride the Cinta Costera bike path. Also, Ubers are inexpensive, Overall a great educational and fun experience.
