We were received by Elisabeth who explained everything about the apartment and answered to all our questions. She was very polite and easy going.
The apartment is very well located in the center of the city, close to the bull fighting ring and 10m walking distance to the cathedral. There are plenty of tapas bars/restaurants around the corner.
Parking could be a problem, but there is the "Mercado" very near with garage for a reasonable price.
Seville is a beautiful city to visit and the choice of Fredrico's apartment was the right one.
