Our First Spider in this apartment: what is it?

Hi Guys!

Because our new apartment is higher up (4th floor instead of 2nd) and immediately less surrounded by grass, bushes and trees (only 2 sides of the building instead of 4), we were a bit concerned that we wouldn't get many of our nice insect-eating friends around... therefore, we were all happy, 2 evenings ago, to see that little beauty walking on the living-room walls I took it in a glass and put it outside on one of the plants on the balcony (the spiders we "had" before hibernated and/or made their nests there). The photos aren't good at all, I know, but I wanted to share them with you all the same, because I want to know what kind of spider it is... any ideas?? it looks like a sort of wolf-spider to me, but I'm not sure...

- in my "Everyday Beauties" section, I don't mean to make Art Photography, I simply want to share with you the beautiful things I see in my everyday life...
Just to show, and remind myself, that every day has a surprise, a beautiful something awaiting round the corner...
