The address is doubtful. Try asking the office as there are many different versions. " Lo Santiago" Gea y Truyols is about the only thing I can say. There are post boxes at the entrance but no deliveries, nor will there be until the site is fully legal and could take time after that. You would be well advised to get a PO Box at th Post Room in Mercadona Square Los Alcazares rather having to pick post up at Sucina if you don't. Don't hold your breath on the Supermarket. It will have to compete with the excellent one at Polaris La Torre only 7 minutes away and I would have thought the catchment area here with relatively small numbers of residents and visitors would not make it viable after it opens.
Of course no news of Escrituras although there is yet another story that 2 people will pick up their papers next week. I will believe it when I see it as the story has been round hundreds of times!
