Teresa's place is lovely, I had a fantastic long weekend staying there. The location is great, I was able to walk to everything I wanted to see and there were plenty of cafes, bars and restaurants nearby.
The apartment itself is beautifully decorated and has almost everything you'd need for a week away. It was lovely and cool inside, offering refuge from the Seville heat and even though there are bars nearby, it was nice and quiet (especially from the bedroom).
