The flat has many advantages as disavantages. It is located very close to the metro which goes directly to Manhattan, the flat is spacious as well as the room, where there is a very comfortable bed. Kitchen is well equipped with quality furniture as It Is the bathroom.
If you have a ligh sleep, resting will be difficult as the metro is not underground and runs very close to the building, the sourranding neighbourhood is a bit unpleasant and it will take you at least 15 min walking to get in the nice area of Williamsburg.
Be aware hosts do not appreciate if you leave your door (even just slightly) open when going back and forth from the toilet (which is private but outside the room) and they might even close it for you. Also, notice that if you need to leave the luggages a few extra hours you will be charged 30 dollars for a "late check out". However, if within this time you need ten minutes to change a t-shirt before travelling you might be asked to leave. So, definitely it was a great occasion for an affordable accommodation in NYC, but as we did not feel very welcomed in the flat, we will not choose it a second time.
