Hi GerryW2W
I did stop at this place. The front door was locked with an arrow to the side as I went down the side a small "Muebles" van was driving away, couldn't find anyone else to ask?
First impressions it looks like a factory where they make beutiful glass and the front is a showroom, and maybe made to order for the Muebles furniture shops. I don't know maybe "joe bloggs" from the street can bye from them.
What I thought was colourful windmills were all made of glass cones. They did have some unique beautiful things in there I must say.
Sorry I wasn't much help, but if you or anyone else can find out any more I would like to know too now , it has intrigued me.
