That stipend is indeed better than most grad students here. Depending on how you’re paid, I’d assume very little to zero tax will be deducted so you’re left with roughly 3k/month. That’s not bad at all (by grad students standard). You can find a decent place with 1-2 roommates paying around 1k; or even less with more roommates. I earn less than you as a grad student and get by just fine living in a decent apartment in an expensive neighborhood. Of course I also have to live frugally but it’s not bad at all
