You could not ask for a better location in the heart of Madrid. Close to absolutely everything, we were continually surprised at how easy the access was to everything we wanted to do. The hosts were exceptionally responsive and gracious and the apartment was exactly as described. The only thing I will note is that, given it’s in the heart of the city, and Madrid is a late night town, you will experience noise at night. Nothing that earplugs can’t handle however.
