Actually is better than Mir was.
It is just psychological pressure you have to deal with, I can tell you though, they are some tough people be in space for so long, is like going on submarine, takes tough to conquer fears.

I think they have way more room than on a submarine. And for a lot less crew. (Unless they close off all the ‘rooms’ like my grandma did so she didn’t have to heat them.)
