We had a wonderful stay at Miguel's apartment. He was very polite and quick in responding. The apartment is in the center-center of Seville, just 5 min walking to the cathedral and Triana.
The only watch out for future guests is that you can hear everything through the walls; from floor to floor and from the street. The street was somewhat noisy on a Sunday at midnight, so I imagine on a Thu, Fri or Sat it could get pretty loud until late.
