There are too many good reasons to love this place - the space is very tastefully done, bed is wonderfully comfortable that you will hate getting out of, the location is fantastic - just barely two minutes walk to the Cathedral and seconds away from all the hip restaurants and bars!
The only caveat to that is the place is on top of a bar so it can be a bit noisy at night, but walking around Seville will wear you out so that shouldn't be much of a botheration as you'll knock yourself out as soon as you hit the supercomfy bed!
