Miguel has a very nice apartment in a great area, less than 10 minutes from Gran Via and Puerta del Sol. You can walk everywhere from there.
The apartment is small, cozy, but well designed so that there is closet, drawer space to put things away; something that I don't necessarily find in bigger accommdations.
A great shower, especially, for a small place.
Miguel is a good hosts, easy to communicate with and helpful with information.
