Sergio is really a great host. His place is near the Atocha Renfe Station as you can walk to his place in less than 10 mins. The metro stations are near and same goes for the tourist attractions. Everything is walkable from his place - the sights, the shopping and the food. Great place to stay. Most importantly Sergio has been really nice assisting us and also has asked us whether we are okay on the second day by texting us. His place is clean and well-equipped. In short BRILLIANT!!!!
