I've stayed at Sunset beach resort before, and would recommend it. It is just out of Patong, at Kalim Beach. There is a free transfer into Patong ever hour or so, until 9pm. Across the road there are lots of food carts, with really cheap food. From fruit shakes to spring rolls, noodles and more. The pool is large, with lots of palm trees for shade. All the staff are helpful. It's not 5 star resort, but it is great value for money.
