I went to Alicante for my last five days in Spain
Where they have not only one castle, or old fort, but two
Where I spent far too much of my time
No, seriously, I did
Because there were beautiful views, and a lot of history, and, and, and... castles!
Or, to be honest, forts.
I met up with three people from Couchsurfing and spoke only Spanish with them. One of them, Ana, took me to see the second castle, the biggest one, where I ended up spending some hours at least, of every one of my remaining days in the city. I spent the weekend couchsurfing with lovely Susana, who took me to a different beach, who taught me how to make gazpacho, and went with me to a Couchsurfing language exchange event. She also needed some time to do her preparations for class, since she's a music teacher, and since she lived just behind the big castle, I went up there a few hours to read my book, look at the view, and climb tiny paths and stairs.
In the end, I was wearing a cardigan while walking outside at midday, in 25 degrees and sunshine. This was when I knew I'd been in Spain for a long time, and needed to go home. And I did.
