Esther's AirBNB is absolutely Amazing. The location is phenomenal, just off Grand Via in the heart of the city, yet super quiet. Wonderful bed, fantastic air conditioners/heaters. Madrid is cold this time of year but the ambient temperature of the flat was always nice and warm. The apartment actually was what it looked like too, and had a great little Nespresso machine for coffee when we woke up. I cannot recommend it enough and would stay here again in a heart beat. In fact we did extend our stay an additional night as we loved the apartment and the city so much!
