I have to start by saying that Luis is an outstanding host that goes out of his way to help guests. Communication is excellent and he responds quickly to issues or questions. He even made an appointment for me when I had phone issues. The flat is in an older building but it's clean and Luis is working hard to continue to make it nicer. The bed was comfortable and there were enough covers for Mexico city's cool nights. The location is excellent, there's an Oxxo around the block and several restaurants within 5 minutes walk. The metro is also nearby if you want and Medellin market also an easy walking distance.
