The place is a very short distance from the Retiro Park, within walking distance of the metro, bus stops, plenty of cafés and bars, El Museo del Prado, La Plaza de Cibelles, and all the shopping your heart desires.
Before Miguel accepts your request to host, he will advise you that he smokes in the house. You can smell it from in the living room but not in your bedroom. Overall, I was very comfortable and enjoyed my time during my stay.
