Dear Sir, first of all, I cannot understand how you expect a beautiful apartment to remain unoccupied indefinitely.
As for the heat, there is heat 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 landlady!
Please be so kind as to send a check for the full amount of $500, or I’ll be forced to contact your current landlady
