I'd rate this about a 3.5. I really enjoyed reading it, especially as a lot of it aligns with how I think about experiencing places and then translating that into my paintings. If you're going to read this, you just have to do so with a grain of salt because of the way she makes declarations throughout.
It kind of petered out at the end, as I find books of this type - a dive into both history and culture with a personal slant - can do. But I still loved it overall.

This is my rating scale:
5 masterpiece
4 holy crap that's good
3 would recommend to a friend
2 not a complete waste of time
1 eh
