I most definitely recommend staying with Carmen! She is incredibly welcoming and helpful - the day I arrived she let me know of several monuments that were free on Mondays, and made sure I felt at home. She told me about a person on a famous actor’s crew that stays with her when they come to Seville, despite being asked to stay at the hotel with the rest - and I understand why! It’s location couldn’t be better, I walked everywhere without a problem during my one week stay. Cleanliness is 10/10 and so is hospitality. I have no complaints whatsoever. Stay here if you’re coming to Seville!
