Rent for Apartment

A man met a beautiful girl and she agreed to spend the night with him  for $500. So, they spent the night together. In the morning, before he left,  he told the girl that he did not have any cash with him, but that he  would have his secretary write a check and mail it to her, calling the payment  "Rent for Apartment." 
On the way to the office, he regretted what he had done, realizing that the whole event was not worth the price. So, he sent a check for $250  and enclosed a note: 

"Dear Madam: Enclosed you will find a check in the amount of $250 for rent of your                     apartment. I am not sending the amount agreed upon because when I rented the                     apartment, I was under the impression that: 
    1. It had never been occupied; 
    2. There was plenty of heat; 
    3. It was small enough to make me cozy and at home. 
        Last night, however, I found out that it had been previously occupied,  that there wasn't any heat, and that         it was entirely too large."  
         Upon receipt of the note, the girl immediately sent back the following reply:
       "Dear Sir: First of all, I cannot understand how you expect such a beautiful apartment to remain         unoccupied indefinitely. As for the heat, there is plenty of it if you know how to turn it on.         Regarding the space, the apartment is indeed of regular size, but if you don't have enough         furniture to fill it, please don't blame the landlord.
