Not stayed at either,but have considered them in the past.The Jabeque is about 5 mins walk along the prom to the centre of Figueretas (beachside).
The big advantage of this place is that all of the apartments have good sea views.
Strangely though,lots of bookers give a studio option! although there are no studios? Might be worth thinking about that,for instance if you arrived and were told they they are overbooked (or whatever excuse)...
They are also a lot closer to pdb if that is an interest? A downside is that they may be a bit noisy these days!
Don't know what Lux Mar is like for noise,but I guess you would.
