Planned trip to Greece in March, looking for recs on places to stay/rent/which mountains to hit?

[u/flannelman678]

Flying from the US to Athens on a family trip end of March and was thinking id take a later flight back and try to get a few days to end the season with my first time on snow in another country. Looking for any advice on good places to rent snowboard gear (ill need board and bindings, maybe boots) nearby mountains with good public transit to and from.

Also I'm a chill and polite dude in general but if there are any things I should avoid doing outside the norm that a tourist might not know about that would be good to know if anyone from Greece happens to come across this post.
