Why are the man and the woman discussing the apartment?

Ring bell’s ringing.
W: Hello?
M: Hello, I’m calling about the apartment that was advertised in the paper this morning. Is it still available?
W: There were two, a three bedroom and a two bedroom. But the larger one has been rented.
M: Oh, that’s OK. I was only interested in the two bedroom. Can you tell me what it’s like?
W: Well it is quite spacious and has sun most of the day. It’s really cheerful. It also has kitchen and there’s plenty of closet space.
M: Sounds good. The ads said the rent was 525 dollars a month. Does that include heat and electricity?
W: No, tenants have to pay their own utilities.
M: I see, and what about parking?
W: That’s no problem at all. Each tenant is assigned a particular space, and that space is there as long as they stay in the apartment.
M: Great! Given how rents are these days, this seems almost too good to be true.
W: Listen, why don’t you come over tomorrow and see for yourself? Ring my buzzer number 16. I’ll be in all morning.
M: Fine, see you then.
