I would highly recommend staying with Puerta cathedral. Check in was extremely easy and friendly, and they were able to let us check in early. They even upgraded our suite when we mentioned it was our honeymoon. The suite was gorgeous, perfectly located and had all the amenities you could need. Air conditioning was super effective, which was very important in a hot city like Seville. The unit was extremely clean, and had trendy decor. They provided good local tips, and if you’re staying with them you can access a beautiful rooftop terrace with a great view of the cathedral. Overall it was a wonderful experience.
