The owner gave us a wrong room key during the check in and the day after he said that it was our fault and even tried to get us to pay extra for that.
He switch to Spanish, when we tried to explain to him, that he gave us the key and that we did not just take a random key from the check-in counter.
The swimming pool was a semi-public shared between the hotel and private houses around.
There was no bar or restaurant or room service available when we were there.
There wasn't any bar at all by the pool, like stated in the description.
The best thing was the owner recommendation for at restaurant. Which turned out to his or somehow related to him. But it was good food.
Finally, at Calafell everything happens near the beach, this area is very dull, find something closer to the beach, where there are restaurants and shops nearby.
