You need to keep your answer short and to the point, don't include any other unnecessary information or wording.
Possibly "that will be fine, just let me know your expected time of arrival". It doesn't mean you have to be there when he arrives, you could be out GALing and then come home, in fact I wouldn't be there, I would come back after he has arrived, assuming he has a key to the house.
Before you reply post your answer here for everyone to see first and advise.
