We highly recommend Antonio's place. We had some trouble finding a parking place. We called Antonio and he came to us immediately, guiding us to a parking garage nearby. The appartment is located in the middle of the old city, so a very good starting point for exploring Sevilla. The appartment was tidy, clean, quiet at night, had good bed and has all the basics you need for a few days in sevilla. The showerhead was a bit low, but me and my mate are tall Dutch guys, so I guess this is not really a point of criticism ;-)
