We had a great stay in Brooklyn, also due to Raymonds apartment. It's really very good located, less than 5 minutes walk to convinient and fast subway A-line, in a sympatic and quiet neighbourhood. Very convinient is also the small store of Raymond and family downstairs, were it's possible to buy everything you need, including snacks, coffee and breakfast. So you can reach Raymond also easily.
The apartment is large and has a good atmosphere, although it's simple in equipment and mobiliary, and some details would need a little improvement. Don't expect luxury, so you'll feel fine.
Also be aware that 2 o teh 3 sleeping rooms are to the street, so it's not quiet.
Overall, we had a great stay and would return there, for sure next time in NY!
