The location of this appartment could not be better for exploring Madrid. From Puerta del Sol you can reach almost all sights by foot. We were very happy with our stay altogether as the appartment was accomodating and clean. Since Bibiana & Gigi were not in town, we had the place to ourself. The only drawback of our stay was that our bedroom was right under the roof, making it fairly hot. If you come to Madrid in August (the month everbody leaves the city...) you should definitely take this in to consideration.
