The house is very big and comfortable. Located just 5 minutes walking from the central plaza del Sol (metro stop). Anyway we moved on foot almost all the time because in 20minute walking you can reach every area of the city center and all the main attractions.
Sonia was really helpful with our needs and very understanding despite some inconveniences. I didn't had the chance to meet her because my flight landed later then the others one. That's why for necessity the communication took place also between other members of my group and was always very good.
Hope to come back.
