Carlos's place is awesome! The location is excellent, within 15 minutes walk to all of Madrid's main plazas & attractions and just a couple of minutes to Gran Via. There are so many options to eat & drink within a block of the apartment, grocery stores also within a few hundred meters in a few directions. Very easy access by the Metro on a couple of different lines - located at Santo Domingo station, but also very close to Callo and Plaza Espana. Carlos was very sweet to meet us in person and show us around the apartment and to explain how everything worked. It was well furnished with everything you would need to prepare a meal at home. We'd stay again for sure!
