That all depends on what you want,
If you want to spend your holiday with english people and drunken people then yes it deffinately is the right place to do,
It is also wuite a way to ibiza town, there are busses evey eveing and during the day though so you will not have a problem to get into town, or you could take a taxi there aswell which will cost you though.
It is your decision but i would say that if you are planning to stay for a week or longer go to playa den bossa and then go to sat antonio just for a day or two to see what it is like, to be there all the time can be tooooo much, depending on what you want.
