Ask HN: Co-working spaces in Europe suitable for a short stay?

I have some time off coming up, and I want to spend it working on a couple of small side projects to put on my CV. I have a vague idea of combining this with a holiday somewhere interesting in Europe. I'm imagining a residential co-working space. Somewhere nice and quiet to work and sleep but with a few like-minded souls around to chat to, as I don't want to be a total recluse. I know these places exist but they often seem to be geared more towards long-term startups than itinerant visitors. It also needs to be quite cheap! Thanks in advance.
