My parents' first time in the US found this the best way to explore NY! The neighbourhood is deeper in Brooklyn nevertheless we felt safe and my parents made it back home late evening alone without any issues at all on numerous occasions. Neighbours say hi and are friendly. Due to the location it is harder to hop in and out and you will probably leave in the morning and come back in the evening. The station is just 10 minutes away. There is no aircon but the big fans in the flat will provide comfort. The place is nice and clean.
