We stayed at the finca of Marga with five people for eight nights and had such a nice time. The house is super cozy and offers all you need for a pleasant stay. The view is really beautiful especially when the sun sets behind the mountains. The communication was always very kind and helpful.
We would definitely recommend the house to groups or families - for kids the pool and garden are just perfect!
But you would need a car to get to the house and cities/beaches nearby.
