This island/islet being called "Hjälp" (Swedish for "help") seems unlikely (but not impossible). Should be verified.

There is now a building covering part of where this parking space used to be. The parking space also extends further to the south. Proper survey is required.

Verify cycle way locations around here, differs between zoom levels.

I believe it is possible to drive from Borgmästargatan to Bredgatan (going south), in which case there should be a connecting road here. Someone need to check this though.

The 1+2 road doesn't end here, it continues up to almost the intersection with road 50 (as of spring 2015). Imagery is out of date as well.

amenity2 is not a valid tag, what would a better tagging scheme here be? amenity does not appear to take a ;-separated list either (or at least JOSM presets stop working if you try that)

This building possibly doesn't exist. Needs verification on the ground. Aerial imagery is conflicting between zoom levels.
