We stayed at the Finca with two adults, one child and one baby and had a very good time. It's max 35 -40 minutes to drive to any beach (with a car, which one definitely needs).
The outside area is large, so privacy is no problem. There's even a chicken "farm", so we had three fresh eggs :-) Little surprises can be found everywhere, so it's worth wandering around the outside area.
The sleepings rooms are nice, the beds as well. There a a few small things to improve (like shelves in the two newer bathrooms, the noisy aroma facility and the pool which is rather small), but all in all it's a beautiful place.
Also, Vicenta is very kind and helpful. She even bought a baby bed when she heard that we would be coming with our newborn. And she and her husband quickly came to the airport when we noticed that we forgot to leave all the keys. So they'll do what they can to make it a great holiday.
You shouldn't forget to protect yourself against mosquitos, but that's a problem you'll have almost everywhere on the island.
Thanks for the hospitality!
