Is this book suitable to physics majors with calculus, linear algebra, differential equations background? I'm "familiar" with basic analysis i.e Abbott, but I don't do analysis every time since I'm a physics major.

No. It assumes a background in analysis including measure theory. It was originally taught as the fourth in a series of graduate level analysis courses at Princeton. The first three were somewhat independent of each other and had similar prerequisites, but this one does require material from the others or from a similar source.

This first chapter assumes the reader is familiar with measure spaces, sigma-algebras, etc.

If you want a book on basic functional analysis at the level you're asking, I recommend Applied Functional Analysis by D.H. Griffel.

Thanks for your opinion, I've looked into Introduction to Topology and Modern Analysis by George F. Simmons, and it has chapters on basic functional analysis, as well as of course topology. What do you think about it?
