The apartment is in an unbeatable place in Madrid. At the foot of the building there are places to eat, drink and have fun. The Santa Sofía museum is within walking distance, as are the parks and the botanical garden. Also from the airport it is convenient to get by bus to the Atocha station.
Warning, it's a few floors to get there, which is uncomfortable if you come with a lot of luggage.
The site was clean and fully equipped to make our stay very pleasant.
