Why couldn’t the woman find a desirable 3-bedroom apartment?

M: This is it. I know that it is smaller than you wanted, but it is one of the nicest apartments in the building.
W: Does it have three bedrooms?
M: No. There are two. The master bedroom is quite spacious though. Maybe you could let the children share the larger room, and you and your husband could use the smaller one.
W: I suppose that I could do that.
M: A three-bedroom apartment will be difficult to find.
W: Yes, I know. Believe me, I have been looking for over a week. The few three-bedroom apartments available are either extremely expensive or the owner won’t allow children as tenants.
M: Well, the owner allows two children in this apartment complex.
W: Aren’t you the owner?
M: No. I’m the manager. I live here, too, on the first floor of the building.
W: Oh. That’s nice. Then if anything gets broken ...
M: Just leave a note on my door.
W: You said that the rent would be $ 460 a month. Does that include any of the utilities?
M: Yes. It includes gas.
W: This sounds better and better. But before I sign a lease I would like for my husband to see it.
M: Why not stop by with him this evening? I won’t get off work until 7.
W: Oh, that would be wonderful.
