I need some translations, your help will be welcome

I told him that you will come to London.

He asked me where will we meet.

I asked him if you can come to his house. He said "no problem, she can come when she wants".

He already said that you can sleep there. If you want to.

He is very sweet and comprehensive and he speaks English fluently.

He said "Are you sure she will come ? I don´t believe it !"

You can also bring your friends, to sleep in his house. He has places, don´t worry about that.

Thank you in advance
