Myself and a friend stayed a week here recently and would highly recommend it. It is exactly as described on AirBnB - an amazing apartment in a great neighbourhood handy to some awesome bars on Bedford Ave plus our personal favourites, the Radegast Hall & Biergarten and Union Pool. We were out in Manhattan all day every day and had a couple of nights out there but always preferred to come back to this part of Williamsburg and barhop around. Transport into Manhattan from here could not be easier with the L Train from Graham Ave (a few mins walk from Thomas's) taking you direct to Union Square in 10 mins or further to the West Village in 15.
It was very easy to check in/out of the apartment and catch the metro to/from JFK. No complaints at all from two very happy campers.
