TITLE: book for metric spaces
QUESTION [6 upvotes]: Can anybody suggest me a good book on Metric Spaces. Although I am not new to this subject, but want to polish my knowledge. I want a book which can clearly clear my basics. I want to start from the basics. Kindly suggest me. Thanks a lot.

REPLY [3 votes]: I suggest "Introductory Functional Analysis With Applications" By "Erwin Kreyszig". Its 1st Chapter gives a very nice introduction to Metric Spaces... Good Luck
