In keeping with the Mazunte vibe, this language school is a relaxed, friendly place where you can start classes any day and study as intensively as you like. Run by a Mexican-German nonprofit organization, which also gives free English classes to villagers, it has a lovely breezy hilltop site centered on a beautiful big palapa (thatch-roofed) area.
One-on-one classes are available any time (M$2000 for a 10-hour week) and the school can help arrange accommodations in family-run guesthouses nearby (from M$100 to M$200 per night). For courses for two people using the same teacher, you'll pay M$1600 each. The school is 400m inland off the main road, signposted beside the bridge in the middle of Mazunte.
