We had an almost perfect stay at Mari's place with our two kids (9 and 5). Why do I write almost? Well, the first two nights, it was raining like hell, which was really unusual. It was even so hard, that some water found the way inside the house through the chimney. But Mari and her husband took care of it right away. Other than that it was just perfect. A lovely place and the pool was just perfect for our boys. Also the two bbq-places are perfect for preparing great food outside.
Even though the location is not directly at the beach, I believe it is really great. You need a car, but then it is very close to the highway, so you can reach a lot of destinations pretty quick. Also you are quickly there from the airport, when you arrive. Llucmajor is within 5 minutes driving distance, you can go for shopping and food there.
Mari and her husband are perfect hosts and Mari's daughter gave us good recommendations on food, beaches, what to do.
