Thank you very much to Maria and her sons. We have enjoyed every minute in a very calm place. We were 4 adults plus our 7 months old baby.
The finca is equipped quite basic, the interieur is not too fancy, but everything necessary was there. Because of our baby, Maria brought an extra mixer and cooking pot. Highly appreciated! If you go there, make sure to bring mosquito spray or even a net (depending on the season). The smaller house closeby was occupied by 2 different parties within the 8 days of stay. First a small family, then a group of italian guys. But we did not come in each other ways at the pool.
To reach the finca, you have to drive through narrow alleys, steep turns and cute villages and it is an adventure for itself. I would go there again and recommend it to everyone that is looking for some rest.
