Also northern lights should be spectacular.

This is what I like over here:
- Big city but you can walk almost everywhere - Weather is great - Airport is 20min subway from city centre - People are friendly, most speak some sort of english - Tech scene is getting better every year - No gentrification yet
There are advantages on being on central or northern europe instead, but if I was in my 20s I would definitely come to Lisbon.
That said, god I love Denmark.
However, if you decide to live outside of Lisbon where rents are very high, that amount of money is enough for you to live well and even save some money if you're somewhat frugal. Also, the weather is usually quite nice here, and if you're into that kind of things, there's a booming tech scene is Lisbon (web summit is here for this week).
Unfortunately, most of the jobs people take here are on outsourcing companies, but there is an increasing number of jobs available on local startups. If you're planning to move here, check jobs in http://landing.jobs/ (mostly startups).
