The place of Jaime, Roma, is perfect to discover the city. Not too far from a Metro Station (hospital general - 10/15mn) and in a quiet place. The apartment is placed on a roof top, so you can enjoy the terrace. Nice neighborhood.. Good and fast communication.
The flow of the shower and the basin in the kitchen is a bit low but if you're alone, that's not a big problem.
A small, but good place to sleep in Mexico DF.
