Pilar was an excellent host, we arrived at her place around 3:00 in the morning, she was kind with us and helped with everything, after 4 nights spent there we kindly recommend her.
The apartment is cozy and clean, and it is close to Puerta del Angel metro station and you can reach the city center in a few minutes.
If you arrive in the night, after 1:30, you can reach her place with the N19 night bus from Cibeles.
