Omar's place is a nice place to stay. They welcomed me personally and there were a few bottles of water, tea and some snacks. Which were nice after my flight. The kitchen was well equipped and had everything I needed. The shower was nice and warm and towels, soap and shampoo were provided.
It was relatively clean and spacious. Some chairs were a bit damaged but it didn't bother me. The walls with the upstairs neighbors are very thin. They started the music around 6am and everything from them could be heard clearly. At 6 am the smell of fresh omelets (or something with eggs) and blending of juices started too. I'm not sure if the neighbors were permanent or if they were Airb&b guests too.
The neighborhood was ok, far from the city so I needed an Uber to move. It an ok location, but you better stay a bit closer to the center. I stayed here for a week and it's a bit too long if you want to explore the exciting places of Mexico City. I spent around 10 dollar per day on Ubers. If you add it to your daily budget for an AirBnB, you probably find a nice place near the city center.
