Our group had a seamless, and great stay at Sergio's space. He was easy to communicate with and went out of his way to coordinate our early arrival so we could leave our bags somewhere. The space is clean, as pictured and very comfortable for our group of 5. The patio with it's expansive vista was another fantastic bonus. It is right next to a major intersection so it was a little noisy with the windows open but the apartment was well insulated with the windows closed. The location just next to Atocha made it incredibly easy to both explore Madrid and get in and out of town.
