I am so glad to find this book. An English woman who started dancing in her 40s has written a book of really good tips on how to make sure you have a happy time and blissful dancing when you go to Buenos Aires. (This is not always easy to do.)
She has 11 smart tips for happiness + how to find the right places for you to dance with a detailed guide to the weekly milongas. She also has a website with updates.
Here’s her website with links for how to buy the book.
