Luis' apartment is located very good, only few minutes away from a central aerobus/bus/metro station. We didn't meet Luis personally but could communicate via Airbnb without any problem, Luis always responded quickly. We got the keys and an introduction without any waiting time.
We felt safe here. No traffic noise since it's on the backside of the house. Unfortunately we could hear the neighbours. They seem to be nice people with nice kids - but they were loud; we were happy to have ear plugs. No problem if you plan to return after midnight. The apartment has windows but nearly no daylight - good in hot summers, I guess. Getting fresh air though the windows is not guaranteed. Cleanliness could be improved (but it was NOT really dirty).
In general I can recommend it (with comments).
