The Alfonso XIII is a great hotel. We had an award stay there, got upgraded as golds to a very nice room, nice amenity (bottle of wine). Hotel is in great location in Sevilla--few blocks to the Cathedral, very close to Alcazar, great location. And the breakfast buffet is expensive, but probably the best I have ever had. Anything you could possibly want there. Nice pool, an oasis in the middle of the city, protected by walls and trees from the street, great for cooling down after some hot sightseeing.
