The room is basically the living room that has a single bed placed in the middle. Be aware that this is a shared apartment, so you have your own room but the bathrooms are shared. I think there were two other rooms being rented. Bathroom and room was fairly clean. There is also no lock to your room. I had someone confusingly open my door early in the morning and closed it right away when he saw I was in the bed, a little worrisome during that brief time.
It was fine for a nights stay especially since I can take the 101 bus from the airport to the rental for 1.50 EU, total of 15 min travel time. And the metro is also very close to bring you to city center.
Juan also showed me the space and other important things to note around the house.
