We loved our stay at Miguel's flat. It was beautifully decorated, filled with all the necessities and had the best location. It was very secure, and had the friendliest doorman name Joaquin.
Miguel is a wonderful host, easy to deal with, always quick to respond. The language barrier did not prevent us from having a pleasant conversation and our exchanges on the AirBnB messaging app always left me with a smile.
If you're in Madrid we highly recommend staying here.
