We had a very nice stay in Madrid. Jesus is an awesome host! The communication with him was very smooth and he gave us all the information that we needed (including how to get from the airport and around the neighborhood). Our plane was 1h late and he waited for us at the apartment - thanks! The apartment has a great location (8min walk to Plaza Mayor), very close to La Latina metro station (and with connections, 50 min from the airport with the metro). The neighborhood feels safe and you can find a lot of restaurants and markets around. On Sunday's it is in the center of El Rastro market which is awesome.
