Not just a photo

This is a photo of the city of Barcelona. I was there in August for my second trip alone. Beyond the fact that it is beautiful, this picture is a nice memory of that journey. Indeed, it was taken by a British guy I met in this great, almost secret place in northern Barcelona where you have a 360-degree view of the city.
He was smoking a joint as we were admiring the landscape. He offered to shoot the photo, which he said would be awesome. He was right.
We chatted for an half hour about the fact he had been living in Barcelona for more than 10 years as well as travel, and the fact that, in his opinion, the Sagrada Familia will remain an eternal work in progress. This is one of the most beautiful moments I had along my last trip!

"Indeed" should be used to confirm the audience's expected suspicions or explicit suspicions. The sentence is in which you used it is perfect without it.

Never say "an half hour". It should be "a half-hour" or "half an hour".

When something is "up to someone", it means that it is that person's choice or responsibility. When "it" is "down to something/someone", that means that "it"(the situation) is out of options other than that person or thing. Alternatively, you could say, "It's come down to something/someone".

Little Talks by Of Monsters and Men is a great song. It doesn't contain much confusing language, and it's sung as a dialogue.

Putting up with someone is like tolerating them. Dealing with someone can mean resolving some sort of conflict with or involving that person, or keeping that person in line, or out of trouble.

This phrase means that how the speaker uses the money in a couple of months depends on how well things are going for him/her at that time.
