Do not hesitate, the Atico of Luis and Mar is perfect for your stay in Sevilla: astonishing view, extra clean, nice decorations, great terasse and very kind and flexible host that shares his favorite addresses in the city.
Many places require reservation. We missed the aire of Sevilla because we haven't booked.
Casa Cuesta has great tapas and it is 10 minutes by walking from the apartment.
If we come back to Sevilla we will definitely stay at Luis and Mar Atico.
