Ask HN: Nice place to work for a month near the beach with good wifi in Europe?

I am a contractor based in London who is taking some time off to work on a few of my own ideas.

I am planning on doing this from a few different locations around Europe and wanted to check if the HN community had any suggestions.

Requirements:

  1) Close to the beach
  2) Not a big city
  3) Good wifi

I plan to rent an apartment with wifi through airbnb for a month but if you know of coworking space which meets my requirements please let me know.
