Catalina was a welcoming host and quickly responded to questions. Our Spanish is not great, so translated messages worked well.
It is a nice house in secluded surroundings. Your are truly away from everything. We stayed here with a 8 month old baby and 4 year old child. The cold stone floor was maybe not the best for baby, but it seems that most Mallorcan houses have this. The 4 year old loves exploring the garden.
The road to the house is very narrow, our rented Peugeot 2008 could make it, but anything bigger would be pushing it. Timid drivers might feel overwhelmed at first.
If you want to drive to see other towns and places on the island, the roads out of Estellencs are very winding, so car sickness was a bit of an issue for us. The views from the road are incredible, though.
There are quite a few biting insects, so bring insect repellant.
