I believe this is an exceptional book to follow up after you have taken a basic course in real analysis.
This has the apt topics that are needed for an Economics PhD student.
Highlights of this book are the following -
1. Engaging problems at the end of each topic and not at the end of the chapter.
2. It usually has important remarks that are made after each theorem or a result, which if taken note of, can make the student understand the depth of each term in a theorem or a definition.

This book is simply awesome. The geometric ideas behind each n every topic attracts any Math students. If u're doing a toplogy course I prefer that u should read this book. It's very helpful for getting basic ideas in topology..
