the W is basically the same hotel as Grand Sheraton Walkerhill. however, the W rooms are relatively new and much better. Also i have stayed at the Sheraton D-Cube and it is very nice as well. The D-cube is near times square and is directly above a subway line. The hotel itself is situated on floors 28-41 of a high rise building. The other ones i have not stayed at, but I have heard the Westin Chosun is top of the line.
