Postal service.

It's fine, put one on wall outside your casa

Many thanks Beanie

This really depends on where you live as few domiciles in .spain have Post delivered direct to house. A post box, at the post office or others offering this service us the norm. In the village where I live householders contributed to a bank of post boxes in the centre if the village. Prior to this residents had to collect mail from the main postal depot.

Which would be relevant if he asked about your village, but as I answered in Sucina it goes to your casa
