Hello Jan!
Thank you for the feedback.
I removed the descriptions now. I thought it could be nice to know what the buillding had been before, but maybe that's not a necessary info. In two cases I added the building type.

I also removed the "f.d." in front of the names I had added it. In these cases, we still say e.g. Läkarvillan, even if it's no doctor living in the house anymore.

By the way, do you think I should let someone review my edits when submitting them? I feel sure about what I add, but I now see that I might not do some technical details "as you should". (I'm relatively new to OSM.)
