This apartment is definitely the best place one can choose to stay at in Madrid!
The apartment looks exactly like on the photos. It is perfectly located in the center of the city, 1 min walk from Gran Via, though as it faces the inner yard it's quite calm.
Jero met us at the apartment and gave very useful tips. He was very responsive and very convenient to communicate with before our stay.
I would definitely recommend this apartment to those who are planning to visit Madrid!
