This is a great Airbnb to explore downtown Madrid. It’s the absolute best location. Everything is within walking distance. We never used public transportation to get to the sites due to it all being so close to the apartment. Everything went great. Good check in, clean place.
Of course it is mentioned that this apartment is small, and it definitely is. My husband and I stayed here a week, which was plenty. I wouldn’t have stayed there longer than a week due to the small space. But the week we were there was great! My only real complaint was the bed was very squeaky. If you’re a solo traveler this might not even bother you, but as a couple it was a little hard to sleep.
