ABSOLUTLEY WONDERFUL!
If you are lucky enough to sign up for a retreat at Vista Mundo - DO IT!! The center itself is located just off the "Highway of Heaven and Hummingbirds" and has some of the best views in Costa Rica. Teresa and her staff are kind, compassionate, and responsive. They anticipated my needs and exceeded my expectations when I asked for anything. I also recommend getting the meal plan - it allowed me to focus on my healing without worrying about what I was going to eat on any given day. AND the food was delicious and catered to my unique diet.
Do yourself a favor and take the time to go to Vista Mundo, participate in a retreat, and reap the benefits for years to come!
