I spent 6 weeks at Marias place and you couldn't ask for a better location. The area is safe, centrally located and surrounded by stuff to do. Check in is simple because there was a digital lock. The building is nice with a friendly staff.
The space is basic with a comfortable bed and the apartment is very quiet. The "dining" table is actually a credenza surrounded by six chairs. It would function for two but it won't be comfortable. They should equip the apartment with a water filter.
Overall I have no regrets and would probably stay there again if I returned to CDMX for a shorter stay. If you want an economical place to crash for a week or so and don't need to do a lot of cooking this is a good choice.
