The communication with the host was great. Cristina always replied immediatly. The locatin is perfect if you want to stay central - it's only a few minutes walking distance from Puerta del Sol, Malasana (a district I would absolutely recommend for having drinks or breakfast), Tribunal or Chueca. But not only the location was great - the apartment is equipped with everything you need. I would definitely recommend it and would perhaps book it again if I come back to Madrid.
