We loved it. You CANNOT beat this location if you want to experience the old center of Seville. You're a short walk from the Alcazar, the Setas, cathedrals, and endless restaurants and bars.
Check-in was easy. The apartment was surprisingly quiet for being in the middle of everything. It was clean, cute, and comfortable. The small touches were appreciated, especially the sewing kit, which was super handy when my backpack ripped. Wifi was fast. Because the windows open to a courtyard, it doesn't brighten up until late morning, so it's easy to oversleep -- just remember to set your alarm. :)
The plaza just steps away has Olmo (ice cream), Empanadas Argentina, and Casa Toni (lunch/dinner) - all highly recommended!
