Sonia is super nice, responsive and helpful all time. Very flexible on check in and check out arrangement. The apartment is very nice, comfortable and clean. Great location and super close to Plaza de Espana metro station. Many main attractions like the Royal Palace, Gran via, Puerta de Sol, Plaza Mayor in walking distance; supermarket and many nice restaurants nearby. We enjoyed staying at hers very much and would definitely recommend her place. :) Thank you Sonia!
