This is a very nice apartment, very close to Center attractions. We can walk to all major Madrid's attractions: Puerta del Sol, Prado Museum, Plaza Major, Gran Via or Royal Palace.
Apartment has everything you need.
One thing that I like very much was the access to apartment. You will have an app on your smartphone to unlock main entrance or apartment's door.
The host will communicate with you clearly and if you forget to complete the traveler's form he will give you a kind reminder. :)
Thank you Rodrigo for everything.
