To come home to

Dear teachers,

"It's a great room to come home to at the end of the day."

Suppose a girl is home-staying and she likes the room the host family prepared for her,

and she wrote the above sentence in her diary.

I want to understand about the to .

I can feel if this to is missing, then something is wanted here,

but I don't get the grammer used here.

It is a great room>>OK, for what?

To come home to it (=the room)

Does the to relates like this?

Warmest regards,
