Thank you so much for uploading this, especially nice to see the entire suite here - I have spent so much time looking for all the guitar arrangments of this piece and am still missin Sevilla and Castilla.
If I'm honest, I prefer these pieces played on the guitar, but they're great on piano too. I find piano easier than guitar and I've been agonising over learning Cadiz on guitar for whenever I'm doing my AS performance assessment. But playing a few of these would be ideal because they're higher than the standard my exam board ask for (they ask for grade 5) and these pieces have a lot of character so I could do a nice interpretation of them. I especially love Asturias - it's a nightmare to play on guitar because of the speed and high positions but it looks much more playable when scored for piano :)
