Hi Lukey,
You cant really go to far wrong with Figuerettes for a holiday location as its got an amazing beach (the longest on the island), a lot of shops and supermarkets for if you are going self catering, and a great deal of night life, and best of all is only a 15 miniute walk from Evissa or Ibiza Old Town!
Figurettes is also around 15 minutes from Platja d'en Bossa which also as some great shops, supermarkets and bars and one of the best clubs on the island Space!
Talamanca is a nice place too but doesnt seem to have as much to offer and like Figurettes is around a 15-20 miniute walk to the Old Town. Make sure though that if you do stay in Talamanca that you get some water in the resort before walking to town as there are very few shops on the way, whereas Figurettes has lots dotted around from the town to the capital itself.
Hope this helps, if you need any more info just ask.
Marc
