I’ve just made something using a mixture of Limelight, OpenStreetMap, UIkit, and some other gubbins.
It’s working for me on all the devices I’ve tried, but before I develop it more (which is going to take a lot of time) I want to check I’ve not missed anything.
Please go here: Casa Elana Torrox Townhouse Guest Area.
Scroll down and click on the “Buses” link. (see screenshot)
Once the Buses section opens click on the button that says “Click Here To See Bus Stop On Map”.
What should happen next is you scroll down the page to @Jannis OpenStreetMap stack, and the popup for the bus stop should be open on the map.
Please check on whatever devices you have to hand.
