The set used for the Sophia and Dorothy's Brooklyn apartment had been used a few times in the series before this episode aired. In all past episodes, however, the Petrillo's were said to have lived in a house. This is evident since the set used is for a two story house. However, in this episode it is clearly stated and shown that the Petrillo's lived in an apartment. Yet the same two story interior set is used. The set is way to big and very unrealistic especially since the establishing shot of the Petrillo's building shows it to be a tenement style building. No tenement apartments in Brooklyn came anywhere near the size of this set nor would any of them be two stories.
The episode title "Clinton Avenue Memories" infers that the Petrillo's lived along Clinton Avenue in Brooklyn. Clinton Avenue runs through the Brooklyn neighborhoods of Fort Greene and Clinton Hill. However, in past episodes Sophia claimed that the Petrillo's lived in Canarsie a neighborhood where Clinton Avenue runs nowhere near.
