I stayed at Robert's flat for a month while in NYC for work. The flat is small, and minimally but tastefully furnished. Very comfortable bed and very fast wifi! Plenty of closet space too. The building and unit are new, so all of the appliances and fixtures are quite nice. Quick walk to 2 express train stops that will take you to either the east or west side of Manhattan, and of course plenty of Uber/Lyft type services come here.
A word about the safety issue that others mentioned: I lived in this area of Harlem for several years before relocating out of NYC, and specifically chose Robert's flat because I know the neighborhood well. In all of the years I lived there, and during the month I stayed this time, I had zero safety issues or ever even felt unsafe. That said, the building is across from public housing projects, and this area of Harlem is not a wealthy neighborhood like Soho or Tribeca. This does not de facto make the neighborhood unsafe, and like I said, as a single female I never had problems. However, if you are totally unfamiliar with NYC and are expecting a more recognized tourist neighborhood, this isn't it.
