UPDATED 14:35 22/11/18 - I have been told that the IKEA may be to the left of the Repsol garage rather than the right. Also, the whole area is supposed to become another shopping centre.
The other day I was talking to someone about the IKEA shop that is due to open in Almería towards the end of 2019. Neither of us knew for certain where it was going to be located. So I have had a poke around on the internet. Apparently it is going to be at the top of Calle Belén. Near a roundabout with a Repsol garage. It looks like this is very close to the 443km turn off from the motorway. You can see my guess of the approximate location on the map above (that I lifted from Google maps).
