My parents and I stayed for 1 week and really wish it was for longer! The location is great, less than 10 mins to the main beach Cala Galdana, but our favourite was walking along the Camí de cavalls to Cala Mitjana which is less than 20 mins (it's probably the most beautiful beach, but very crowded even in mid September) and further that direction is Cala trebalúger which was the quietest as it's more remote, it definitely has a more rugged feel, but still beautiful. The water turns brown after heavy rain causing the river nearby to burst, so just a tip if you prefer the water to not be muddy.
The apartment was spacious and well equipped with nice views from the balcony and living room. A tip for finding the apartment as it's the first 37B on the left. The road is a little confusing as the house numbers have no direction.
The only problem we had was with the ants, I'm not sure if this is normal for the island or not, but there were many and you couldn't leave anything out of the fridge which was a little problematic. We put down cinnamon, lemon juice and cucumber peels to deter them and that worked for sometime.
Apart from that I do recommend the apartment to anyone who enjoys walking especially, and family's. We would go back again.
