The apartment is right close to the Cathedral, the Aire spa, and the Alcazar. The trek from the train station is around 20 minutes walk, pretty flat and easy.
Give yourself time to get lost in the winding streets. There are plenty of amazing things to stumble onto.
Milagros was a fantastic host! Very knowledgeable of the area with great suggestions for places to eat and things to see. The apartment was spacious and wonderful! We would stay here again!
