Good: great location, safe neighborhood, supermarket a couple of blocks away, Utica Avenue metro station a short walk away, everything is as described in the listing, water filter, big fridge, air conditioning, small balcony for smoking (sorry Raymond, we totally forgot to throw away the cup of butts on our way out), excellent value for the price shown.
Could be better/tips for guests: due to no fault of the host's I'd suggest getting some good ear plugs as the location is right on a busy crossroads and, for some reason, people just _love_ driving around with their music blaring from the car's window. The toilet is right by the living room, so pooping can be a bit awkward (I had no idea that that is important but, turns out, it totally is). Don't leave food lying around because that's how you get ants. Again, minor things that I wish we knew, in an otherwise great appartment.
Bad/deal breakers: Nothing.
If you want to explore Brooklyn and have an easy way onto Manhattan I'd definitely recommend the place.
