One that comes to mind we enjoyed, generally undervisited by North Americans from what I can tell, is RCI's Feriecentret Ragaleje Klit in Denmark #2056. It's on a beautiful beach, close enough to Copenhagen that you can take the train in a couple of times during yr stay to visit its major sites (or drive, but we didn't, tho we used a car for further travel that week), + see other beautiful parts of Denmark. You can even take a ferry to Sweden for a day (we planned to, but ran out of time). The 2-BR units all have beautiful views, not fancy but very clean and comfortable, almost endless daylight in summer.
Another maybe: Ferienclub Grundlsee (Mondi) #2578, you can visit Salzburg from there, but again it's more of a rural than urban timeshare.
There are others I loved, but not near urban areas, rather in spectacular rural areas such as UK's Lake District, France's Dordogne, etc.
Just got back from Perle Veneziane (Venice) where we landed a 3-BR, and had space to spare w/4 people. Not fancy but no complaints, other than the # of rainy days! But we finally got to witness and experience "Acqua Alta" ...
Edited to add: if you're wondering what acqua alta is, here's our youtube:
