I spend one night at Sergio's appartment and I was surprised, because it looks even better than the pictures. It looks all quite new, with good materials , neat, really clean, and the bed is excellent too, I slept very well, despite being located next to Atocha which is a busy place, there was no noise inside. By the way the location is perfect, located next to Atocha train Station and Retiro Park. Sergio is one of the bests hosts I've ever met, he's a warm, nice and helpful person, he answered all my texts very quickly, he could adapt to my schedule for the meeting, he also speaks a perfect English. I strongly recommend Sergio's appartement
