We stayed at Merce's place for a week over Christmas with our two kids. Great views, good kitchen including an espresso machine, and lots of space. The walk to the shops on Los Olas is about 15 minutes and about 20 to the beach. We were usually carry tons of beach stuff so we drove down and parked in the municipal lot for about $5.
The pool is relatively small but the kids enjoyed it and we didn't see anyone else in it
