We considered those apts this year, but went down market instead!!
Having stayed in Figueratas the last two years, I can highly reccomend the area, a 10 min walk along the beach to Bora Bora one direction, 10-15 minute walk to Ibiza Town the other ddirection.
We checked out the apts you mention this year, and they looked ok.
Dependant on budget, we spoke to a few peeps who sstayed in Jabeque (same area), and they were well impressed. The new hotel Eviza looked well chilled out (same area), again depends on budget.
Previous year we stayed in Play Sol II, that was 9/10, top floor, sea view with sun from 10:00am till 7:00pm on our balcony. Was full this year tho, don't stay in the following, in the same area:
Play Sol I
Can't recommend the area highly enough.
Next year if we don't do the villa thing with a crowd, we will go with Jabeque or Playa Sol II
Hope this helps.
