We had a fabulous stay in Alison's apartment. It is modern and well decorated, and left us wanting for nothing. We didn't have the pleasure of meeting Alison herself, but her husband Carlo was very welcoming and kind.
The area really could not be any better, walking distance to all the major attractions. The Parasol was a five minute walk, and the cathedral and Real Alcazar about 15 minutes. There are a ton of charming little restaurants nearby, and we took her recommendation of Taberna Colonial, which was very good and just at the top of the street.
We definitely recommend staying here, and will definitely return on our next trip to Sevilla!
