The dependance of Pina Rosa is nice.
It's rustic and facing the Etna.
Sadly we had to leave after one night as there was no wifi and since there is also no signal in that place it wasn't doable for us.
Another point we didn't like was the fact that this "dependance" is attached to their house and only a thin door separates the bed area from their house so we can hear them too clearly for my taste and that wasn't enjoyable.
Overall a good place but make sure to go with good weather on your side.
