Six stars for Antonio as a host. He is very friendly and caring, gave me many information about places to see and searched for interested places to my daughter.
The apartment is very clean and quiet, all provided as described. Very good place if you travel with a child - few steps to Retiro Park (ducks, turtles and peacocks), near to metro station or bus, 10-15 minutes through the park to museums: Prado, Reina Sofia, Thyssen-Bornemisza, Palacio de Cibeles etc. I strongly recommend.
