Sponsorship letter and House accomodation

Hi,

I am writing sponsorship letter for my wife who will travel along with me. In my CoS letter I have company address where I will work .Hotel booking is not done as I am yet to get visa..

In sponsorship letter can I only mention that I will sponsor her accommodation ? Or I should say She would be staying with me in the house accommodation located at below address

And mention address in my CoS (Note this is not hotel address but work location address in CoS)

Thanks
Milind

If you are traveling together why do you need a letter?
