Marina is a lovely person who was really helpful both before arrival and during my stay, massages were replied very quickly with a lot of useful informations.
The location is very near to subway line Q that brings one directly to Union Square (the trip is about 40 minutes altogether).
One shouldn't expect an area full of bars and restaurants, but on the Courtelyou road (ca. 10-15 minutes by foot) there are some really nice places for a coffee or for a drink or dinner.
Although the flat is not in a free-standing Victorian home typical for Ditmas Park, I would recommend it first and foremost for those who'd like to stay in a neighborhood like Ditmas Park, being still well connected to Manhattan -- and don't mind to share the flat with two cats. The ocean at Coney Island can be reached in about 25 minutes with the Q line.

The photos describe quite well the atmosphere of the flat.
