From the general point of view, the mark is high. The accomodation was above expectation, the same can be said about the quality of food itself.
Maybe, during our stay in the hotel, we were unfortunate enough to dine with some elderly tourists who took the stand, that "their"
table, was the table where they had to dine regardeless of the number or needs of other people.

My partner and I stayed at the Copacabana Hotel for a week, half board in August. The Hotel's quite old but still tidy and clean. Lots of nationalities stayed there - I think we were the only English there :-). There's a nice little bar area and small pool, but always enough sun loungers! If you don't fancy the pool area there's always the lovely beach at the bottom of the road. Got very busy early in the morning and late afternoon but still plenty of room to put you towels down. There's also lots of little boats that go to other parts of the Costa Brava which were reasonably priced and enjoyable - well worth going on.
The food in the resturant was basic but edible - there always seemed to be a queue at the weekends (especially Sunday night) to get in there at 7:30pm. In the week there was a steady flow of people eating there. But if you don't fancy this there is always pleny of bars and restaurants in walking distance to the hotel.
Ideally located if you want to get to see Barcelona (weel worth a visit), via bus and train and also other seaside towns on the Costa Brava.
