Our stay in Biniaraix was wonderful. Communication was fast, helpful and friendly, the coordinates to find the house very clear, the house absolutley beautiful, the orange orchard a delight, and we had a lovely time.
If you want to park the car in the car port in the garden, consider getting as small a car as possible (generally good advice in Mallorca), not because the car port is small (it easily fits two cars), but because the street leading into it is super narrow.
The rooms and beds are cozy, the heating system is effective (you just have to trust it; it takes a while to reach the living room, but the dining room heats up quickly); the kitchen is decently stocked with cooking ware (even if some of the pots don't work on the induction stove). The shower makes up for its need for descaling with high water pressure. There were some ants - but that's nature for you :).
There is plenty of space for six people, and the hiking trails start right behind the house - brilliant!
