Rebeca's place is very well located, there's bus, metro, train, restaurants, grocery stores, pharmacies, market near by. Downtown, Polanco, Roma are close by.
The apartment complex is small which makes it quiet. Of course there are some loud neighbors but those are very few.
The apartment is cozy and has the basics to spend few days; we stayed for a month and, internet, hot water, electricity didn't fail at all.
I highly recommend this place if you want to feel the real Mexico city life without sacrificing your wallet and your safety.
