Giselle was a wonderful host ! She's lived in 3 continents and is a film-maker. She's a joy to chat with.
A few things to note for the next guess- this room's window is right on the main street so don't choose this place if you're someone who needs to have quiet to sleep or to work because you aren't going to get it here! The musicians and crowds will keep going until the sun comes up, so it's best for someone who plans to be out late enjoying the nightlife.
That being said, the location is truly ideal for anyone who wants to walk to experience the best of Madrid. From here I walked to Sol, Plaza de Cibeles, the royal gardens, Parque del Retiro, 7th of July plaza and to the Rastro Market among other places. You truly will be in the heart of everything.
