The apartment is very well located, right in the center of Madrid, with quick access to the metro, the great advantage is being able to go directly from the airport to the apartment via the metro. The apartment was clean, although with a strong damp odor, there is no air conditioning so the nights are very hot inside the superior room.
The decoration is not the best, the bathroom is great.
If you are going to spend a few days in Madrid and use the apartment only for sleeping is enough.
