There are two standout features of this Airbnb. The first is the location. Right there in the heart of the city, you're close to everything you'd want to see in Sevilla. From the Cathedral, to the Setas, amazing food, and world class shopping. The second is Matthias, who is a really great guy: laid back, but totally attentive. He helped us with planning parking, getting extra bed sheets, and understanding when my niece came for a day of or visit. His communication skills are really remarkable.
(If there were a third, it would be the amazing terrace, but since it was December we didn't use it much.)
All around great stay. 5/5 would recommend.
