Apartment Rental

Hi, I am looking to holiday in Los Alcazares in August last two weeks for around 10 nights, but can’t find a suitable property. There will be 7 of us, 4 adults and 3 kids. We either want to rent two apartments close by in the same complex with a shared pool or a single apartment/house/villa close to the beach and shops. I would like something nice and budget is 2-3k. Are there any local holiday rental sites or can anyone advise on where is best?

Thanks

Luke
