It will cost almost 185,000 euros and will be located on Calle Arquitecto Julián Laguna. This is the road that starts between the golf hotel and Mercadona. So I guess the tourist office will be located underneath Porto Fino.
El Ejido will be paying 40% of the cost with the rest coming from the Junta de Andalucía.
The article also mentioned that the number of summer visitors to Almerimar tripled last year. It was certainly busier here last summer. I feel that the extra events organised by the Junta Local of Almerimar helped will this.
On reading the article it looks to me that at present this is only a submission requesting funding from the Junta de Andalucía. Hopefully it will get approval in due course.
