The place was very clean and in the center of everything... you can take the metro directly from the airport and you get off at the opera metro right near the apartment. There were little touches such as breakfast. The host replied instantly when we were trying to find the place! I would book again when I come back to Spain.
One thing I must add, which it wasn’t a problem for us was that there’s a lot of stairs to come up to the attic apartment and no elevator...
I was very happy with the location!!
