Pilar's apartment is right in the old town section of Santa Cruz, close to the Cathedral and the Alcazar - each just a 4 minute walk. Many great tapas also nearby. Everything we came to Sevilla for. The building is beautiful - with a central courtyard with plants and a fountain. The rooftop had a great view of the Giraldi tower. The apartment is lovely and well equipped.
Pilar is an extremely thoughtful host who had thought of everything you might need for your stay. She has great recommendations and even had the kitchen stocked with coffee, cold water and a treat for us!
The only problem we had was the door to the courtyard: the door sticks and we had difficulty getting it open. One night a neighbor heard us banging the door and, fortunately, came down to let us in. And one point to remember: if you check in after 21:00, there is an extra charge of 20 EUR for late check-in. This is the only time we have experienced a late check-in fee in Spain.
All in all, we enjoyed our stay in a great location!
