We had a fantastic time staying a week in Lorenzo's apartment which is within 15mins walk to all main sights. Atocha station, Sol plaza, Prado museum, Reina Sofia museum & more. Lots of restaurants & bars in nearby streets too & it felt like a very safe area. Lorenzo speaks English well & greeted us on arrival. He even bought a kettle when I enquired if there was one! The stairs up to the bed may not suit someone with bad knees/legs, but it was otherwise great. The internet worked well too. There is a communal courtyard in the building and the kitchen has a washing machine & dishwasher. I'd highly recommend staying here.
