I covered a bulk of the book in my analysis course, as well as more in free time. The book provides a solid introduction to analysis. Compared to, say, Abbott's understanding analysis, its less of a hand-held experience, and the author expects the reader to take greater responsibility of their own learning. However, I personally liked the rigorous and concise writing style. It provides a nice middle ground between Abbott's book, and Baby Rudin, being approachable by beginners, while accommodating the developing skills of the reader.
All in all, I would recommend this book to the dedicated beginner looking for a solid introduction to analysis.
