There is one word missing in each line of the text

There is one word missing in each line of the text. Where does the missing word go? What could it be? Last year I went to ->for my holiday. (Spain) I spent the fist week Seville staying with a couple of friends, and then I a train to Barcelona, where I spent another ten days. It is beautiful city and I had a marvellous time. I stayed in a very hotel right in the centre, but I didn't mind spending a lot money because it is a wonderful and very convenient. My brother recommended it; he goes Spain a lot and he stays anywhere else.
