The apartment is right in the centre of Seville, very close to the Cathedral but also to Triana and Guadalquiver. It could be noisy just after midnight when restaurants close but that's the case with any place it the centre of any city. The apartment itself is good and functional, but if you have mobility issues and find walking up and down the stairs difficult that might not be an ideal place for you.
Aitana was a great host. I especially appreciate that she was quick to response, always available and ready to help and solve problems that inevitably occur if you stay longer (we stay for a month) I also like the fact that she always had time for a little conversation and that she seems generally pleased to see us when we bumped into each other. I would highly recommend it.
