“"Can't wait to go back"”
We stayed at La Perla in August 2010. We had an amazing experience. The room we got was super comfortable, clean and nice. The receptionist is very helpful and agreeable. The Es Canar beach is just 3 minutes walk form the hotel; Cala Nova is only 10 minutes walk and we thought it was better. Also, only a 15-20 minutes walk can take you to Cala Martina which also is pretty and quiet. You have plenty of restaurants and bars nearby as well as supermarkets and shops. If you want to visit Formentera, there are daily ferrys so there's no need to go to Ibiza or Santa Eulalia, you can just catch it there.
In addition, if you can rent a car or scooter you can visit any other part of the island quite easily. I'll love to go back next year
