i really enjoyed staying at Wasim's. it's located right in the center of Harlem (very cool), and is close to all the hot spots in the neighborhood.
additionally, it's right by all the transit, so jetting to other parts of Manhattan or NYC isn't that hard.
the apartment itself is really cool with a colorful British edge (think James Bond).
Wasim is a delightful host who is easy to reach and a great source of tips for travelers.
HIGHLY RECOMMENDED ;-)
