The beach is wonderful, very family oriented and not at all crowded like other beaches in Ibiza, but with little choice when it comes to accomodation.
Grupotel is quite outdated in terms of facilities, but provides a nice beach view. The staff was the most unpleaseant part of the experience, being very rude in general and very rude specifically at the restaurant - where their main duty was to clean tables and quickly prepare them for the next guest (which creates a canteen atmosphere).
Restaurant hours are too early and quite short, resulting in literally being sent out with a 'you need to leave' by the staff when the meal time was up (9:30pm at dinner). Even if you were finishing eating/drinking, they would repeatedly ask you out until you'd leave the table. Staff would then stay eating alone at the restaurant until late hours.
Although we brought our own shower products, they wouldn't even replace the small amenities to e.g. wash hands.
