I stayed at the Westin Market St. for just two nights, but it was perfect for my business trip. The hotel itself is very nice with easy access to downtown and not much different in distance to our office from the Union Sq. location of the Westin St. Francis (this one is actually preferred given tourists in that area). The service was great upon check in and I got a smaller but top floor room with panoramic views. Reception talked me through what was available still given it was late and let me choose. The water pressure in the room was a little bit light, but otherwise, the room was very comfortable. I had two meals at the restaurant and both were very good! I'll be back!
