We had a fantastic stay at Nacho's place. The location is incredibly convenient if you want to be in the northern part of the city, and at the same time it's right next to the Cuzco subway station so you can get anywhere in town easily. The apartment is on the 10th floor so it's very quiet and has great light throughout the day (plus beautiful sunrises!). It was a bit chilly so we dd not get to enjoy the terrace, but it would be a great spot to sit in warmer weather. We felt right at home. Rooms and bathrooms are modern and fuctional, and the kitchen is well equipped. Nacho was very responsive and accommodating. We would definitely stay here next time we are back in Madrid.
