Good location near Santa Justa train station, you can get there in few minutes walking, you might be interested in that specially if your are planning to travel by the train to Cordoba or Granada. Also, airport bus "EA" stops front of the station and Alcazar is almost 25 minutes walk or you can take a taxi to get there for 5 euros which is reasonable.
Mrs. Mercedes was nice and though she couldn't communicate in English but she was able to explain most of what I needed.
