Some friends have stayed at the Beni Beach apartments and said that they were nice.
They are on the Pontiente Beach but not really near the night life.
you could google them and take a look to see what you think and find out which companies deal with them.

As Sue says Beni Beach are further away. I have stayed in these apartments and they are very nice but if you want to get to the night life you would need a taxi or it would take you 30/40 mins walking. Avenida Apartment I would say are a bit nearer to the night life without being too near. I have also stayed in these, they are nice but can be a bit noisey.

Alpha roooms, Thomson, Wintersunshine holidays,cosmos holidays all do both of these apartments.

I dont really know much about the apartment situation in Benidorm, always having stayed in Hotels, however if you want to be near enough to the nightlife ie 10/15mins walk, i still think you would be better looking towards the Levante End, rather than Poniente personally!
