I took the family for a stay at the ETM Private Wellness Retreat in Costa Rica. The villa is more beautiful than the pictures shows very spacious. The owner and the staff were attentive and freindly, local restaurant, market and shops minutes away. You think the pool is the main attraction, think again. Overall ETM Private Wellness Retreat is a place a plan on going back.
