Everything, location, very comfortable beds, excellent pool amenities

Nothing

The outside areas (look of the buildings, pool area) are beautiful and the location is great (as it's near Ciutadella, which is way better than Mahon, even though the area of Cala en Blanes itself is too English for my taste). The area is the perfect headquarters if you plan to go around the island a lot. You get everything you need in the apartment and free parking is available basically everywhere.

The apartment was clean, but we had to clean some surfaces ourselves (table, chairs and shelf under the mirror), as they had not been cleaned. There's a lot of humidity in the area and it would be good to have some sort of dehumidifier: we used to stay out all day long and our things inside got wet (also during the night), as it's not really feasible to leave the windows open because there are no bug screens (if you plan to use the pool and to stay in the area, this issue won't affect you). The cover of the front terrace is not water proof, so if it rains the table and chairs get all wet and the terrace is basically unusable. Beware of the sprinklers when you get home late (around midnight): you have to slalom around then not to get wet. If there were sensors to temporarily stop them, we were not able to find them.

The location, the facilities and the people.

Beautiful place. Well maintained garden and clean pool. They provided a baby chair and cod for our son (8 months) which was really nice! Clean and everything you needed. A few restaurants in walking distance and also a beach nearby. There are only a few appartements so it was very quiet and we had a lot of privacy.

The only down side was the road in front of the location. On Friday and Saturday there seemed to be quite some traffic at night.
