My husband and I could not have asked for a better place to stay during our first trip to Seville! We stayed 4 nights (we extended for another night because it was just so special), and only wish we could have stayed longer. Everything was just perfect! Leticia met us as soon as we arrived and showed us around the whole place. She then gave us a really great introduction to the city, along with fantastic food recommendations (though the two restaurants directly beneath the apartment were amazing). She also organised tickets to a great flamenco show on our first night! Communication was smooth and we heard back almost immediately anytime we messaged.
As for the apartment, it is truly unique and could only enhance a stay in Seville. It was in the middle of everything (the Alcaza and Cathedral were right around the corner), yet extremely quiet at night so no problems sleeping. I would highly highly recommend this place and would definitely stay again when we next visit Seville!
