Sergio's place is amazing. The terrace is wonderful in the sun and there is absolutely everything you could need for a comfortable stay, down to shampoo, shower gel, plenty of towels, coffee - just everything you could possibly need! My brother said the sofa bed was super comfortable. My other brother and myself found our rooms and beds perfect and comfy! It was a busy road but I slept so well. We decided to go to Córdoba on Saturday and being opposite Atocha was great, literally 10mins and you're in the Renfe part of the station waiting for your train! Was also useful for the Vincente Calderon as it's a couple of stops to Piramides. There are plenty of supermarkets and bars around and walking up the Calle Atocha means you're at the Plaza Mayor in about 20mins. I would recommend Sergio's place without a doubt. The check in was easy to arrange and the apartment is great. Absolutely would book again 100%.
