The flat is in the middle of Williamsburg but just one block away from bars etc. - so it is even quiet there! Plus 10 minutes to Metro or Ferry! We felt totally safe.
We did not meet the host in person, but he made sure everything went smoothly.
The pics are exactly as in reality. It was super clean. The apartment is not brandnew and some things might need to be replaced, but that wasn't a big issue. Would totally recommend staying there! Thanks Jarrett!
