This Q has been pretty much answered in a recent post. There are no aparthotels in Cambrils. The closest you will get is Pins Platja in Vilafortuny. Its in a good location just over the road from the beach but entertainment is limited. Lots of privately owned flats nearby in some great spots but entertainment will have to be DIY or go out and about to the bars and hotels. There is nothing to stop you renting a large apartment and going into a local hotel for pool/lounge entertainment as long as you buy the hotels own food and drink.
