where abouts are you planning to stay? If you want cheap then go to the west-end in Ibiza, stayed there couple of yrs ago, for about £10 a night in sept, if you want somewhere a bit nicer & with a pool then go for san antonio further down the Bay, anything from £20 upwards depending on location really. Ibiza Town is about the nicest - had a look on here goes from about £50 a night tho.
