The flat is clean, quiet, and equipped with everything you could need. Nice comfortable bed. You can walk to the Prado and Reina Sofia museums easily, but if like me you have little sense of direction, the metro is five minutes walk away. Mike's tips for local restaurants are really helpful. One thing - there is a short but fairly steep climb away from the flat on leaving. If you have heavy luggage, be sure you can pull it up (and bear in mind there is no lift, so you have two flights of stairs as well) Highly recommended for a very reasonably-priced stay in Madrid.
