I live in Germany and spent almost 8 years in Austria before that & that (60k gbp = 75k eur) would be considered a very good salary for a senior dev here.
Actually I think only rent and public transit are more expensive. Food and entertainment are cheaper than in mainland western Europe and flights from London are pretty cheap as well.
But it's true that the overall cost of living is still much higher than anywhere else in the EU (save maybe Copenhagen or Zurich).
(I'm in London at the moment and I do acknowledge that this place is fucking fabulously expensive).
