Mauricio's place is the best choice for an excellent price. The apartment is super comfortable for two people. It was very clean when we got there and it's an excellent location to explore Ciudad de México (Even the bed was comfortable!).
People on other reviews complain about the noise, but we didn't find it to be a problem. Mauricio even had ear plugs and we brought ours just in case. Street can get loud during the weekend but it's really not that bad. Plus, the AC helps.
Mauricio is a great host and responds very quickly. Check-in/out is simple and the apartment is very safe. The security staff are super friendly. I'm a safety fan and honestly this is the place for it. The location is close to so many places you can reach by walking and close to Insurgentes Metro station, which you can jump into and reach maaaany places around CDMX.
Would definitely book again if we go back to CDMX and if you're thinking about booking it, do it!!
