I highly recommend staying at Maria's place. The apartment itself is spotless, beautifully decorated and extremely cozy. There were muffins and fruits in the kitchen when we got there and the apartment had some very cool appliances such as the water sprays in the shower and the artifical chimney (that was beautiful) . Maria also went way out of her way to help us out -- she volunteered to pick us up from the metro station when we got there and provided ample information on places to visit and things to do in the city. Our luggage was delayed on the way to Seville and as soon as we told her that we were looking for a phone charger, her husband came to lend us one of theirs. It was honestly a remarkable stay with great hosts.
