It so happens I am staying there in a couple weeks from now... I am spending five days in Mexico City with my new Hilton Diamond status and am spending five nights in five different hotels (Hilton Reforma, Hilton Santa Fe, Umbral Centro Histórico, Hampton Inn Centro Histórico, and Doubletree Santa Fe)... for this one, I already spent an extra $10 for a little upgrade from a queen bed to a king bed. I think this hotel is too small to be giving out upgrades, maybe my luck would be better since I opted for a slightly larger bed.
