Alhambra tips wanted, please!

[BellissimoGecko]

Going to Granada for a few days next month. Does anyone have any tips about visiting the Alhambra, eg which tours are best? Other things to do?

Thank you!

We had lunch in a lovely little courtyard inside a tiny restaurant in the grounds, it was lovely.

Don't fall down the stairs to the underground toilets near the ticket office would be my tip. Made the rest of the day rather painful 🙄
