Primark
 

Went there today

Its part of a large shopping mall near Ikea

As for Ikea, go down the E15 Ap7 motorway direction Murcia, watch out for the Ikea signs then turn off the first right turning when you see the new football stadium, don´t worry if you miss that turning take the next one to Ikea and just follow the signs through that shopping complex and you will arrive at the Nueva Condomina where you will find Primark and many other lovely shops.

Yes

It is a shop within the new shopping mall

opposite the ikea site

There is another massive shopping complex between ikea and nueva condomina, it is called Thader and it is fantastic!!! :-)
