I've been here for 3 days for work, the hotel is exactly in the centre of the city, it' very elegant and chic...and sweet-smelling and full of design! My room was big and very bright, also breakfast has been very good, you can choos between continental breakfast or "spanish" one with jamon and bread. We had to use a kind of meeting room, it was very homely.
Last but not least: the terrace from which you can almost touch the Giralda!!!
