The apartment is very clean and well-equipped with washing machine and dryer. Very useful for those who plan to have a long trip in Europe. Bed is comfortable too. The apartment is very well located to the metro station "Callao" and the popular shopping district "Gran Via" which is all within walkable distance. Right below the apartment there is a pastry shop which serves a whole variety of pastries. A good way to start your morning with some pastries on the go. Matias is also very friendly and helpful. Although he didn't meet us personally, he kept in touch and communicate with the visitors. Overall a very good experience. I would strongly recommend to stay in Matias' apartment to anyone who stays in Madrid.
