We loved our stay in Seville and were very lucky to find Luis' place during the April Ferria. He's super responsive and was waiting for us at the front door despite our changing arrival times.
It's great value for money for families or groups (we were a group of five with two couples) and the place is much more spacious than the photos show. It's a nice 15-20 minute walk to the cathedral, and a good supermarket and awesome churreria are just around the corner. I'd definitely stay there again if I go back with friends.
