This hotel is in the north of the city, close to the Chamartin train station. (This hotel chain is known for employment of people with disabilities and it's a wonderful thing.) It's in a quiet neighborhood, about 25 minutes to Puerta del Sol by bus. The #150 stops literally at the end of the hotel driveway, and it will take you directly to the city center and you can get off anywhere along the way to see other sights. We bought a tourist card for 5 days for $29 USD and used it extensively for unlimited rides on the Metro and all city buses. Riding the buses and Metro is very easy and efficient with a good map. The hotel is clean and quiet and adequately equipped with a large tub/shower, a hair dryer, a bidet, a refrigerator, and a restaurant downstairs. It's a short walk to a nearby Metro stop, or you could take the bus mentioned above. Granted, it's not in the center of the city, but we were able to see the city's surrounding residential areas, and some adorable school children, while on the bus each morning. The neighborhood is pleasant to walk in the evenings. Nearby grocery store (Alcampo) provided us with snacks and drinks for the hotel room. We appreciated seeing the "real" Madrid outside of the old city and downtown areas.
