Stayed here with my partner for 11 nights. Upon check in we were shown around the facilities (pool/bar area) and then taken to our apartment. It was just what we wanted and a little bit more. Very spacious in the living area, with air con, a sofa and chairs, TV, radio, kitchenette including washing machine, cooker/grill, toaster, kettle, hob and microwave, a nice balcony (unfortunately there was not much of a view but this didn't bother us as we joined in with what everyone in Nerja seems to do which is be out most of the day and evening - the town is still bristling with families and performers at 1am!). Saying that we did look over a small garden so it wasn't unpleasant to sit out.
The apartments are about 25-30 minutes walk from the beach or town and about 5 minutes walk from the supermarket. We walked everywhere, but for families with small children / those not used to walking so far I would advice renting a car, as Nerja is built on one big hill. It's downhill all the way to the beach/town, and uphill all the way back... and I mean ALL the way! There is a regular bus, we just didn't use it.
The pool area near reception was nice, with a 25m long deep pool, 15m shallower pool and a baby pool. There is another pool but we didn't try that one. It does charge for sunbeds, but there is a grassy area with parasols that you can lay a towel on to avoid the cost.
The beach is lovely and I would recommend spending plenty of time down there, with lots of restaurants and shops.
