This is a really great option if what you're looking for is a centrally located apartment. I loved being so close to the Zócalo, several Metro stops, lots of museums and places to eat and shop. The apartment was super clean and the setup seemed very safe -- with a security card for the building, a helpful doorman, and keys to the apartment. The Internet was fast and easy to connect (I used Skype with no problem), and I slept great in the bed with soft sheets and blankets.
