best book for matric space for self study

Hello!
# By kaplansky called Set Theory and Metric Space.
It's a wonderful book which will be handy on your self study and also it gives you short notes.
# An introduction to metric space and topology by Wilson A Sutherland.
# Topology of Matrix space by S. Kumeresan.
There are a lot of exercises aiding in grasping the material to the core.
I hope these be good resource to you.
But personally I would like to refer the first book.
All the very best.
