Pilar's place is in a great location within Madrid. Right in the middle of La Latina neighborhood (great restaurants and bars and a block from the metro station). Short walking distance to Plaza Mayor and Puerta del Sol -- top attractions in the city.
The apartment was beautiful, clean and had modern amenities. Great little balconies that had French doors that opened to below. Elevator in the building was a huge plus (didn't get that in a lot of other Airbnbs in Spain I stayed in).
Would definitely stay again.
