Mike's place is a wonderful little apartment very close to the center of Madrid pretty much in the heart of Lavapies a great place that offers food drinks and good links to metro bus and trains, if you need it - we walked to the royal Palace via Plaza Major in 33 degree heat and then to the Prado and el retiro the next day when it was even hotter.
We did unfortunately experience some builders above us during our stay that meant any lie-in or siesta was out of the question during the week, you are also very aware of any noises that the upstairs neighbour makes too. We live out in the countryside so not really used to any noises so it may be that we are more affected by it than others.
Mike was very good, great at communications and do take up his recommendations re: food and drinks.
