We stayed at the hostel for a 3 nights and were amazed by how pleasurable it was.

The room was a bit empty, but we didn't need much more than a comfortable bed and Lucia was nice enough to offer me and my wife a double. The room had air-con with heating option, so it was warm during the cold November nights, which was a nice surprise for us. The showers were clean (and there was no problem with hot water) and the kitchen provided us with microwave and portable oven (plus fridge), so we were able to prepare our own meals, which was a great bonus.

Hostel itself is really located close to all important places, like Cathedral, Alcazar or Plaza de Espana. Just a ten minutes of walk or so and you can reach most of the places.

Overall, a superb ratio of quality to price, and a total recommendation if you're looking for something in the center of Seville.
