Carla and her maid Irina were absolutely lovely and were extremely helpful. This is also one of the nicest areas of Madrid, with lots of good restaurants and the Retiro park within 100 yards. Not a stylish apartment, with the layout typical of the area (small rooms off long corridors), but would definitely recommend if you want an authentic experience of living in Madrid while avoiding the hustle and bustle or grunginess of Malasaña/Chueca/Lavapies.
