The stay was amazing. Azucena is a friendly host. She made sure that we have everything we need for our stay. The rooms are spot clean("Monica clean" for those who understand the reference :D). Its right by the Bus station and just 500 mts away from the nearest metro, so getting around Madrid was super easy.
The only drawback that I could find is that The room is in the 4th floor. You have to climb the stairs everytime which is good for cardio lovers :D, but apart from that its the perfect place to stay if you're in Madrid for a few days.
