Highly recommendable for several reasons. We were 3 people - a Manhattan hotel with the need to book two rooms would have cost us a fortune. The apartment has real charme, different from most others we checked out in the area, including a large kitchen and living room. The beds are also better than what you often get in the US. And you get to experience the feel of a real neighborhood, which we liked a lot. The only possible downside can be noise: Depending on the night, the one sleeping in the one-bed-room facing Throop Ave will suffer from nightly noise on the street (the couple in the room facing the courtyard much less so). Also, depending on the winds and fly routes, you will hear starting or landing planes from JFK quite loudly and every few minutes - we experienced that 1 night out of our 7.
The other thing to have in mind is time: It is some 15 or 20 minutes on foot to the nearest subway station (Kingston Throop Ave, 20 min, Bedford Nostrand Ave, 15 min), so if you book to explore Manhattan and want to come back during the day, you need quite some time for that. We were not pressed and were fine with that. Altogether, an excellent value, and we would gladly come back.
