Location is perfect! The apartment is only 1 min away from Gran Via, and it is within walking distance to many tourist spots: Puerta del Sol, Plaza Mayor, etc. We were able to go back to the apartment and take washroom breaks and recharge our phone batteries in between.
Patricia is helpful and respond to our messages really quickly. She gave me some good tips on my excursion to Toledo.
The only area of improvement is the blankets. They did not keep me warm during bedtime.
Aside from the blankets, there is no reason why I would not choose Patricia's flat again. What you see on the airbnb site is what you get!
