There were some people living in the floor above, which is not properly isolated. I had to stay awake until 3 AM one day because there was some religious celebration happening upstairs, and so I could hear their dancing steps. If you happen to meet the neighbour and ask them politely to try keep some generous silence, then you'll good. Hopefully, that happened once and after some discussion things went back to normal.

In general, it's a great experience for someone who wants to feel comfortable and adventurous in NY, meaning that you must love to walk and take public bus or subway in order to feel the real vibe at this big city. So, I strongly recommend this place and their hosts for such experience.

Thanks Shahar and Denis!
