We stayed for four days at Rosa’s and all we can say is: it’s so lovely! The apartment is very clean and smells good, the room had a nice bed and enough space to store our luggage, and most of all the hostess is so kind! Heartwarming stay extremely close to Parque de el Retiro and the main museums (Prado, Reina Sofia). Only a few stops away from Sol by subway. 10/10 would recommend :)
