We had a very nice stay at Ignacio's. The flat was very clean and comfortable, very quiet, though in the middle of the old city of Madrid. It is wonderfully located, all the great places within walking distance. Plenty of little restaurants, small shops and supermarkets around. Ignacio is a fine host, there were flowers to welcome us ! I would definitely recommend the flat except if you travel with babies or if you have disabilities. It's on the fourth floor and there is no lift.
