THIS is the place to stay in Seville! We'd give it 6 of 5 stars.
Great layout with lots of space for our family of 6. There were doors to provide privacy and quiet no matter who was awake and active. Secure with a front door keypad & key to apt door. Safe neighborhood. Perfectly located for an easy walk to all of the main sites, mini market across the street, restaurants around the corner. The hosts were fantastic with communication and even helped us sort parking of our 9 passenger van. Washer/dryer made for easy refresh of laundry. Decor of place thrilled our young adult children (so much that they asked if they could stay permanently).
Access is great with an elevator for one + suitcase, but there are a couple steps to get up to that level.
