Begoña was extremely patient during our check-in process as we were late due to a lost bag at the airport and no wifi to contact her. She and her son were so kind while introducing us to the apartment and Madrid itself. This is probably one of the most central Airbnbs you can find in the city. The apartment itself is very clean and comfortable with some nice amenities and very easy access to the Metro and great restaurants/bars. I would stay here again, no question!
