The place is truly incredible. It is a modern revamp of an old home in the center of Seville. A few things to keep in mind:
1) It is very vertically oriented and each room essentially has its own floor. The stairs are narrow and would be difficult for anyone with mobility issues, though there is an elevator that goes to each floor that suffices. We traveled with someone in a wheelchair and the showers were too small for her bath chair to fit comfortably. That said, the elevator made it possible for her to get around.
2) the location is perfect. You don’t need or want a car and everything is walkable from this location.
3) the space is well decorated and very clean.
Overall, I would recommend this apartment strongly for a group that is traveling without any mobility problems. If you have mobility issues, it’s worth further investigation.
