Asking for a friend

Have a fellow colleague , travelled to Nigeria for the first time last year (Nigerian but born here), met this really "nice" girl. They've been talking since. She doesn't ask for anything but I know he has on the occasion (more than) sent her money. Her living situation is the issue. Her job doesn't pay her much so she is subletting a 1 bedroom apt from a guy according to her works in another state. With the understanding that when he comes to town he stays in the apartment with her. He is currently around and according to her, he stays for a week or two. According to her, it's not an unusual situation in Nigeria as normally her rent would be higher, this way it's not. As I'm not on ground I don't want to give biased advice, those on ground in Nigeria is this common or is it as I think.. Lol Question: Is this accommodation situation usual, that the landlord will come camp for some days. Also he said she is cooking for him.. being a good host as she says

Thanks for responses. So I just let my guy read all the responses. He hasn't eaten all day!!
