Great Experience at Mundo Antiguo Spanish School Cusco

The classes were well taught and professionally run.
Teachers were well trained, knowledgeable, and personable.
The school is well run, with knowledge appropriate, small classes, and extra activities to use Spanish outside classes, for example a language exchange where students speak with locals who want to learn English.

The school arranged my homestay experience at La Casa de Felcie, which exceeded my expectations - a tremendously friendly, generous, helpful, engaging, and witty family with loads of great experiences to share. They also were very amenable to my speaking (my less than perfect) Spanish. I met great people there, both the hosts and other visitors besides myself.
The accommodations were great!
They made great food, three meals a day (if that is part of your package)!
