I totally agree with JT Dublin above, this area in Tenerife is beautiful, it's the one holiday that I keep thinking back on and would love to go back this year (pregnant at the moment so debating it in my mind), the area is fab, I would recommend one of the "Iberostar" hotels, these are a subsidary of a spanish airline but there is a beautiful one by the sea in Los Cristianos and the beach there is def one of the best I've experienced. Namely it is "Torviscas Playa", this is a link to the hotel, take a look, well worth it:
The food is also fab in Tenerife, it's def. one of the cheapest places we've been to for eating out and very good quality for what you're paying.
Best of luck in where you decide to go - I'm sure you will enjoy every minute!!!
