best cs:go map to play with begginers friends?

I would probably recommend dust 2 or just download a small 1v1 map for you and your friend.

dust2 and office are both good maps to teach your friend how to play.

I would personally recommend Dust 2 as it's the most beginner friendly.

i think mirage is the best map

Dust 2, Mirage and possibly Inferno. Popular maps which get played often and easy to get the hang off after you play for a while.

I think mirage is a good option to help them with basics and having fun in my opinion

I think, you should try Inferno

probably mirage or dust2 theses 2 are good maps

Don't play dust 2, it's full of veteran players. Go play mirage!
