Juan Antonio's place is very comfortable and centrally located for your stay in Sevilla. The Cathedral and Royal Palace are practically around the corner. We loved eating breakfast and lunch at Mateos on Mateos Gago St right before you get to the Cathedral. Walking around town is the best way to see the city. We only spent two nights in Sevilla. Will have to come back to see more of this beautiful city.
We almost didn't see the Cathedral inside because we didn't get tickets in advance and there were none available when we went to look for the next day. So we went to mass and although we probably didn't see it all what we saw was amazing and they played the organ for mass. It was wonderful.
