Great location - we could see the beach from our room. The hotel was clean, the staff was friendly, and the beach was steps away! Wish we had stayed longer so we could have enjoyed the pool as well.

Very loud and busy. Room smelled like meldew as did the two other couples rooms in our party. Food in the cafe (empanadas) were not edible, but the wrap I got was good. Music was loud all night long and made it difficult to sleep. Would not recommend.
