Great budget option in Mexico City. The apartment is about 20 -30 minutes by Uber away from all the major sites (Uber was about $5-7 per ride).
This small apartment has all the standard amenities, including a kitchen niche. It faces a quiet narrow courtyard. The next building over is a school, and we had some issues with noise after 7am.
The apartment is about half the price of what you would pay in Condesa and Polanco. The area is safe with plenty of street food. We always felt safe, and liked the residential feel of Roma Sur. It’s not a touristy area and feels more authentic than Centro Historico.
