In Portugal you get a fellowship that covers tuition and a monthly stipend which was increased for the first time in 15 years (by 1.4%) last year. PhD fellows are not considered employees of the University and since the stipend is not really a salary you are stuck in a weird financial situation.
Despite all this, it is enough to live (around 1000 Eur) in most of the country except for the capital (due to house/rent prices have been increasing for the past 2 years at galloping rate), which is where a great number PhD granting institutions are located.
Not to pile up, I've also discovered that you can be granted a PhD fellowship for a project at an host institution that is under equipped (if has any equipment at all) for that project.
