Dulce's flat is well located, very close to the cathedral and the Zocalo of Mexico. It is rather nice and spacious, but it can get really noisy with the really thin windows and the noise from the street. If you are a light sleeper, you should plan to put earplugs at night. Same problem for the light : there is no curtains or blinds sufficiently thick to block the light. At 6 in the morning, the flat is filled with daylight as if there were absolutely nothing on the windows to block it. So for us it was earplugs and sleeping mask... But the building is nice, with a very helpful doorman, and a nice rooftop. It is pretty good value for the price, but don't expect it to be the most resting place in the city !
