Stayed there for a week in february for a good price. Close to the airport (10 min taxi ride) and close to beach, shop, restaurants and bars.
The place had 2 bedrooms, a living room with kitchen (microwave, cooker, toaster, kettle, fridge, cutlery). The outside had a little pateo and the 19 blocks face the swimming pool (To cold for feb though, same as for the beach we thought). Clean and friendly staff, they can help you with bike/car rental, just down the street. For the restaurants, there is a nice stretch with a few good places 5/10 min walk from the appartment, on the left of the beach.
The last one before the chinese does a great Paella/sangria :) the one next door had great fish.
You can find others walking towards the center of town along the seaside, but I wouldn't recommend the ones next to the spar restaurant down the road.
the airport is close but you cannot really hear the planes.
otherwise, a car would be essential to see the island, well worth it.
Also if you have one, there is a beautiful one south of the island, called papagayo.
