Olivier and Arquimedes are great hosts--they made us feel welcome and like invited guests, not renters. Their apartment is light and airy and clean. I LOVE this neighborhood--it is a typical Mexican urban neighborhood with many small shops and restaurants, all catering to the local inhabitants. There is a street one block away that is closed to traffic and has many sidewalk cafes. We ate many fixed-price breakfasts and dinners. The neighborhood is extremely clean and well-guarded--there was usually one policeman at every intersection.

The room is simple and clean with space to store your clothing. The bed was comfortable. Bathroom is shared and clean.

Then, you are 3 pleasant blocks from the Zocalo! Being so close, we ran into all sorts of live music when we strolled up there just to people-watch and sit in the sun.

Two caveats: As mentioned by others, there was loud music on the weekends. If you need real quiet, this is not for you.

Second, the water temperature in the shower was difficult to adjust, and I got blasted with steaming hot or freezing cold water more than once.

Those said, I would stay with Olivier and Arquimedes again in a heartbeat. I can't imagine a better location (at this bargain price) to explore the center of Ciudad Mexico.
