For me beer is best some where between +6 to +8 degrees celcius
No problem with that temperature. I'd prefer more on the 6 side maybe though. The beer I had in Poland though was certainly warmer than that. I'm guessing it was into double digits - I mean at the very least, as far as I'm concerned the bottle should be cool to the touch but it was just kind of ambient.
I'm talking lager only by the way - I realise that other beers are a completely different thing as regards temperature.
