Mexico City hotel recommendations?

[DonJuane]

Note: A relative visited the Frida Kahlo museum yesterday. She arrived at 8:30AM while the museum opens at 10AM. Already there were several hundred in line. She waited 4 1/2 hours to get in. Also a tour bus of Asian people broke in line, security was called and the tour bus patrons refused to move to the end of the line. Quite a ruckus ensued but the issue was not resolved because the entire group even when the guards arrived refused to move back to the end of the line.
