I highly recommend Pelayo and May's place. It's definitely among my favorite Airbnb experiences. The location is excellent, within walking distance of many of Seville's most important sights. The apartment itself has a gorgeous rooftop with views of Seville. It's the penthouse so there's a lot of privacy. Pelayo and May were such warm and welcoming hosts, they were very responsive, and offered many helpful recommendations during our stay. I would definitely return.
