If you are thinking of a few days in Madrid this is a perfect apartment for two! The location is 1 minute walk from a central metro station or if you prefer every where is walkable from here. Cristina is an extremely conscientious host and you will struggle to find better help and advice from a concierge in any top hotel - our trip was memorable for so many reasons - mostly because we took Cristina's advice on restaurants & trips to visit - she will help you book and even rebooked our train back from Toledo when we decided to leave an hour earlier then planned (over the phone/online too) . The restaurants nearby are the best and we found our pattern was to eat local between 9pm-10pm and still have time to refresh ourselves before hitting the bars and streets of downtown Madrid .
If all Airbnb hosts were like this you would never book a hotel again.
Good luck with your stay but you won't need it here !
