The apartmente is located very close to the Atocha Metro...1minute to Reina Sofia. And 5minutes to Prado Museum.
It was very clean and had all that we needed. Is small but complete. I got the key with the neighbor but she is always available in case you need her.
I had a little bit problem with the hot water in the shower, and the lights in the apartment, but Elvira explained and helped us with it. She is very nice.
