We stayed in this appartment for a week while visiting New York. The appartment was really good, it's everything it says in the description, there is plenty of space, good bathroom and a neat small kitchen. The appartment was also exceptionally clean and warm. There is a decent supermarket nearby on Fulton Ave and the Norstand Subway station is close - its handy because that station is on the express line so all trains to Manhattan stop there, I dont think we ever waited longer than 1 minute for a train to arrive.
This area of Brooklyn is not like staying in Brooklyn heights (or on Manhattan) but it was definately a good travel experience.
If you're staying in New York for a week the unlimited 7 day travel pass at $29 is a definite bargain, and if you're planning on visiting most of the big name attractions then the New York City Pass at $79 is also great value - plus in some cases it lets you queue jump to get in quicker.
