They don't make textbooks like this anymore, do they? So pretty and concise and all-you-generally-need and short.
I wouldn't recommend this to beginners; this book would help if accompanied by simple dialogues and more exercises.
For intermediate levels, though, it's just the thing. I finished the Duolingo Danish course (vocabulary intensive with a focus on speaking) right before this and the phonetics/grammar section went to fix any misconceptions I had about word order, adjective declinations, verb forms, conjunctions and the sort. The grammar section was then followed by a short 'common words' (units of measure, for example) section and several short (1-2 pg.) stories in Danish that made for lightly challenging but pleasant reading. Then, the book ended with some twenty-something passages in English, to be translated.
All in all, very neatly done, if I do say so myself.
