You could not find a better location than Olga's place for your sightseeing stay in Madrid. You are 2 blocks from the royal palace, so even when you check in at 3 pm you can still run over and see that. This street is even on the Rick Steve's map so that makes it easier. You can walk to the Prado and back and see Plaza Mayor and Plaza del Sol. Restaurants are everywhere nearby and a little food shop across the street. Apt is clean and well equipped. Staying at Olga's really made our trip navigating Madrid a breeze. We could see what we wanted and get back for a siesta. Highly recommend!
