The location is fantastic!! You'll be right in the heart of old town Seville, with so much to see, and so many restaurants and bars right on your doorstep. Despite this, the apartment is on an interior courtyard so you'll enjoy complete silence and serenity away from the nightlife just outside the front door of the building.
Manuel is a great host with detailed recommendations for where to go to get necessities and places that are worth visiting.
Enjoy your visit to Seville!
