Park slope is a nice, quiet and (apparently) safe neighbourhood. A couple of subway stations located close to the apartment made travel to other parts of Brooklyn and to Manhattan fast and convenient.
The apartment was clean, looked as on the pictures and appeared to have been refurbished quite recently.
Perhaps it should be mentioned that the apartment is in fact at basement/souterrain level, i.e. one floor below those that are shown on the facade photo.
Nick was attentive, available to answer questions and allowed us to check out anytime we wanted on the departing day which was highly appreciated as we had a late flight.
