The place is really clean and modern. I was urgently looking for a place to stay for one night, David and Christina got back to me immediately ! (Thanks again) There is a restaurant right next to the place with amazing seafood called "bodegon de Paco" and pretty cheap too €3 for a main dish !! And to get there from the bus/ train station, I actually took the subway and got out, after about 3 stations, in "El Torcal" station and after that you move up to the Europa Avenue and from there you squeeze between houses till you find the place. Some neighbours saw me looking around and guessed I was looking for the AirBnB place and showed me the right entrance.
Perhaps it would be a good idea to put a picture of the building too in the instructions area. If you actually take the airport express bus, on its way to the city, it passes right in front of the "El Torcal" subway station. The fare for the subway cost €1.65
