We had originally booked another (smaller, cheaper) house, because of a double booking, Cristina offered us this one for the same price. Communication was always quick, though some things were lost in translation. We were a little annoyed by the separate platform through which we had to register, because it didn't work properly and asked for a lot of data.
If you have a car, the finca is a great place to explore the island. Take earplugs if you're a light sleeper (dogs, rooster).
The weather was colder than expected (snowstorm), and only one of the ACs worked as a heater, so we booked the central heating for a few days. 30€ per day seems a bit much to me, but this was clear from the start and worth being warm.
The house is elegantly decorated (even though not as sparkling new as in the pictures) and well equipped for cooking. The missing doors between bathroom and bedroom did bother us a little.
All in all, we were satisfied with our stay, though I'm glad we didn't pay the full price
