Great asset to Airbnb. Olga is a great host. Despite not being in Madrid at the time we were there in, she was always available and very friendly. Anyway, she got everything prepared so well upon our arrival, that we didn't need much additional help. We spent one month in her apartment, and we felt like at home. Very clean, light-filled, and nicely decorated. So comfortable that we'd had like to stay for one month longer. The surrounding area is also one of the best spots in Madrid. You can go everywhere on foot. We barely didn't need to take the metro (subway). We'd repeat without hesitation.
