Great location. Walking distance to main attractions. Only issue is parking but there are long term parking lots within walking distance (if you are lucky and brave enough you might find a free parking space down the narrow streets but that depends on how much you value the bodywork of your car!).
When arriving I would suggest approaching from the west of Seville (the river side). We came from the east and the GPS took us on a harrowing drive through the centre of the old town where directions given by the GPS were confusing to say the least!
We expected to arrive a bit earlier than check in and Juan Antonio kindly agreed to meet us when we arrived.
The apartment was a little noisy but to be expected when you are in the middle of town.
