I think I was the first guest to ever stay here and I paid less than $10 for a night. I didn't know what to expect and was very pleasantly surprised. Alfonso and his assistant Arturo met me right on time. The room and shared areas/bathroom are all quite clean, new construction. The hosts thoughtfully left all the basic necessities available in the room and the bathroom. There is a nice personal touch here, and the location is very secure. There are three sets of doors to pass through from the street and I had keys to all three. The wifi worked well on the roof, which is directly accessible from the room. The water in the sink and shower is hot.
If you are over 1.75 meters(6 feet) then keep in mind that the height of the room is 1.75 meters. I highly recommend staying with Alfonso and Arturo if you're traveling on a budget. There is a big park and a couple nice inexpensive sit-down restaurants directly next to the location. You can walk to the metro station in less than ten minutes. There is lots of air traffic overhead that will cease in the late-night hours. The room was quite quiet during the sleeping hours. This was a good and interesting AirBNB experience for me. Very well done for $10 per night!
