San An is Proper cheap, but dirty and you get what you pay for. Many regret it!!! Ibiza Town is on the other end of the scale, but near loads of good bars, clubs (El Divino and Pacha). A nice Middle point, is Playa D'en Bossa. This has short walking distance from Space and Bora Bora, and a good 24hr bar "Ancient People". This is a looong walk to Ibiza Town or a tiny cab ride(£5), and a long(£15) cab ride to San An. A lot depends on what you want. San An is full of beerboys shagging Sharon and Tracey and then beating them up after they get sicked on (sorry!). Ibiza Town is classy, but with women who could be seen to be up their own arse (picky and unapproachable i mean). Playa D'en Bossa, again, is a combo. A lot of nice girls (or are they?), but full of people aaaaattuvvit (if you cant get off your head in ibiza though, where can you??? Yeeeaaaahhh).
I stayed in Es Vive (the posh-y one in fuengeretas inbetween PDB and IT), and Jet apartments in PDB, and , to be honest, Jet was the nuts. I didn't use the appartments in my 7 days in each, apart from grabbing a couple of hours kip. They both did this amply well, but Jet rooms were much much much bigger, with a sea view, right next to cool 24hr bar Ancient People, space and Bora Bora, and a bit cheaper. In general, its hard finding a hotel that isnt only a short walk from the beach or on it.
