Apartment is excellently positioned for exploring the city - 5 min walk to get to the metro station (either Sol or Tirso de Molina), and anywhere else from there. Sol and Plaza Mayor are both very close to the apartment within walking distance. Also, it's very convenient to reach it from airport.
As it's a short walk from Sol, in smaller street it's easy to have a nice sleep. All amenities are available in apartment, and Jose lives just across the street, and he was at our disposal all the time. It was a pleasant stay.
We would return again. :-)
