The 30 days ticket costs 37 euro. There is no student discount for it unless you have Aktivpass. Then you will be an Aktivpassinhaber which means "The Aktivepass holder". Yes, I am having fun with German. Aktivpass is given to a student from the city after some paperwork, but hey, I am not a student anymore.
There are also other tickets, but I will not dive deeper into the fares subject - everything can be found on the Linz AG website.
When it comes to flat I was lucky. My girlfriend has been studying here for more than a year, so I've found it easily. Maybe some day I will describe how to find a flat in detail. Anyway, I have to register in Linz. That seems to be quite easy - fill up the Meldezettel and get it signed by the flat owner.
What's interesting is that we can get the Wohnbeihilfe from the city which is a money supplement for the rent. Cool. It's 200 euro to split between all the flatmates. Of course the are some requirements. First - appliers can't earn more that 1500 euro by flat. Second - one applier has to be registered on the flat's address as his/her main place (to do so he/she has to show that has 5500 euro on his/her bank account). Third - the flat can't cost more that 7,00 euro per square meter. These are the conditions.
Flat prices are OK. Comparing to Madrid, they are just awesome. For a big room in a 76 square meters flat one can pay from 120-200 euro. Bills would be around 30 euro a month.
I came a year ago to Linz from Madrid to visit my girlfriend. The first feeling about the city was so different from which I actually have. It seemed small and sad, now it feels compact and well organized. It seemed windy and cold, now it feels windy and not so cold. Austria is a very rich country and Linz takes advantage of it in a fantastic way.
By the way I have been to my first job interview at celum. It went great.
