We are 80km south east of Krakow
That's some place in the moutains.
Also, could you give a hint of the climate from November to March in Krakow, please.
Winters are colder in Poland than in France generally. But it's also healthier (at least compared to Paris climate), as long as you wear good clothes.
In Cracow, it should be snowy in that period (November-March), and temperatures on average should be around -5°C (usually between -10°C and +5°C).
The coldest month should be January or February.
You should probably wear warmer clothes than you would in France, but it's alright, Cracow is not Siberia, don't worry.
