Hi EA-payphones! Excellent work spotting this and adding it. Just thought you might like to know that there's actually a specific tag for describing the exact location of a defibrillator. It's 'defibrillator:location'. The information you added to the 'note' tag would perhaps be best added to a 'defibrillator:location' tag instead. :-) More information about other useful tags for AEDs can be found here: https://wiki.openstreetmap.org/wiki/Tag:emergency=defibrillator?uselang=en-GB
Keep up the great work!
