TITLE: Algebraically flavoured functional analysis book
QUESTION [12 upvotes]: I'm looking for a book on functional analysis that would suit someone who is more algebraically/geometrically oriented and seeks to learn the subject with the goal of using it later for geometric analysis and/or topological k-theory (and maybe noncommutative geometry in the far future).
What would be a good book fitting this description?
I have the relevant background in basic measure theory, complex analysis and linear algebra.

REPLY [5 votes]: I believe that

A. Ya. Helemskii, Lectures and Exercises on Functional Analysis, Translations of Mathematical Monographs , vol. 233 (2006).

in conjunction with some standard book such as 

G. K. Pedersen, Analysis Now, Springer-Verlag, (1989).

should suit you well. Note that Pedersen's book itself contains lots of basic information about Banach and operator algebras which is probably what you need.
