Laura's apartment is very compact - especially if you are 188 cms tall like me, you might need to negotiate your way into the bathroom. :-)
Nonetheless, the apartment is very charming and its greatest advantage is its location right in the city center of Madrid - with bars, restaurants and shops on your doorstep. Most sights are walking distance or you can use any of the two nearby Metro stations.
Laura has been a great host, five star communication. It has been a great basecamp for discovering Madrid! Would recommend to others. :-)
