A while ago I spotted a notice on the Almerimar Local Information Facebook page saying Mercadona was going to close for a while for refurbishment. It said they are going to close from 25 February to approximately 10 March.

While I was in Mercadona I asked about this at the checkout as there were no signs up in the shop. The lady serving me said they were closing from 23 February for around 2 weeks.

So it looks like they are definitely closing in late February and early March. However, as yet, I am not sure of the exact dates.
