The Aberdeen Hilton Hotel (Sierra Leone) must be pretty far along in construction. I was walking around Freetown today and my mobile connected to signal called "ABERDEEN HILTON HOTEL" from its wi-fi. The best rumors I have, from local press, suggest a late 2018 opening. Unfortunately, I can't pinpoint location, since I probably covered 20-25 km on my walk, but obviously on Aberdeen and probably around the Cape/Aberdeen Road Circle.
