The flat is located perfectly to visit the city. From there you can walk everywhere (plaza mayor, puerta del sol, prado, palacio real... ) and there are different metro stop in the area (also 5 min from the flat). The flat is really nice and modern, the bed is comfortable and there is also a sofa-bed. The only thing is that the windows face the internal courtyard/internal walls, so there isn't a beautiful view. But on the bright side, you don't hear the noise from the street. Oscar and Vanessa answer quickly to messages and are really helpful!
I recommand it!!
