Does anyone know a great place to stay in the Canary Islands?

My husband and I want a quiet beach holiday for about 2 weeks this July or August and we're thinking of the Canary Islands as we've never been there but we love Spain and have been to a million other Spanish-speaking locations. We'd like somewhere that's easy to fly to from Dublin, has nice sandy white beaches (we know some of the beaches in the Canaries have black sand, not white, so we'd like to stay clear of those) and away from crowds of noisy British and Irish tourists. Last summer we had to put up with an apartment block full of British teenagers blaring loud music at 4am every morning and we don't want a repeat of that. If anyone can recommend a nice spot, with reasonably priced QUIET accommodation, please let us know. Thanks!
