Julio is really a perfect host. He gave me a city map, which was very helpful. He's really friendly and helped me with every problem I had (which have been quite a lot). The flat is really clean and silent. The room has a single bed, a desk and a big window. The area is pretty too as it is just near the Retiro Park. But it also isn't far from the city center. And whit the metro station Ibiza it has a good connection to the rest of Madrid!
