Silvia picked us up from Atocha Station and it was only a 5 minute walk to her apartment.
The neighbourhood is very convenient for traveling by bus and metro and you can reach the center within 15-20 minutes. Also nearby are Spanish Restaurants, supermarkets etc and the Prado and Reina Sofia Museums within walking distance.
From the airport you can catch the Airport Express bus which takes you to Atocha Station.
The apartment itself is small and a bit cramped for four adults but the furnishings were of good quality.
Silvia gave us valuable information on what to see and do which was a great help.
We would like to stay there again if we come back to Madrid. Thanks again Silvia.
