Are these sentences grammar corrected? (お貸し、お借り)


> A: この本をお借りしたいんですが。  
>  B: すみません この本はお貸しできません。

I got a little confused when it comes to these word like お借り、お貸し。




お貸しする is a "humble" way of saying 貸す and similar for お借りする, a "humble" form of
借りる.

There is lots of information on the web about these, for example here on this
site:
