A great little space, 15-20 minutes walk from the main city centre.
While parking is free, it is scarce, and requires careful driving around very narrow streets. Actually it was a lovely introduction to old Sevilla. I suggest that travellers stop at the 'apron' at the entrance to the Calle (it says No Standing but don't worry about that, just use your flashers, and be quick) and check-in/drop off luggage before touring the streets to look for a place to park.
The apartment is well equipped, and Fabio is a gem! He explained all the sights, and gave us some good hints about what to see.
Highly recommended!
