We loved this spacious apartment. Perfect authentic simplicity that feels that you are truly in a historical Spaniard place (with air-condition). The balconies that overlook at the peaceful Doña Elvira plaza as the sun rises were a plus. We walked the cobblestone streets to the Cathedral and the Palacio. Everything was very close to the main attractions. There is a tourist info center near by. We bought our Flamenco show and our tour bus txs there. Tere are plenty of restaurants and little shops, including a Starbucks, where we charged our phones and cool off. We loved the apartment, its locations, and Seville. We definitely recommend it for you and your family.
The only suggestion is to clarify what is the closest drivable plaza since you have to roll your suitcases on the cobblestoned streets for a few blocks. The streets are like a narrow maze so pay attention. Figuring it out was part of the adventure. Thank God it was not too hot.
